It's just LINEAR circuits guys, maybe you shouldn't be EE's if you can't hang!

He had a very bad temper but his teachings are REALLY REALLY good.

He keeps you learning. Good Prof!

His lectures are clear and engaging. He gets the information accross well. His book is the exact opposite, hard to understand. He's a nice guy but has a quick temper, especially when it comes to tardyness and talking in class.

Just go to his office hours, he is a totally different person when he's not trying to indimidate 100+ students in EE170 (the room, not the class)

i had this prof last semester and i must say that he is one of the better prof we have at ths university. but if u sit in his lec u will also notice how rude and short tempered he can really be

Very good lectures, worth going to. Impossible Examinations, very low averages consistenly below %50

Just learn to love him. He quite rude and blunt but he knows his stuff and he also knows how to present it well. What more can you possibly ask for? Tactfulness is something a high level educator should AVOID at all cost and thus you should thank him for being an ****. Just suck it up.

Prof. DeCarlo is easily the best prof I've had so far in EE. He keeps your attention and teaches the subject matter well. As long as you study like a demon for his test and show up for class, you will enjoy his class.

Very helpful

He rocks my world.. if you don't like him.. you won't like any professor and you should re-evaulate yourself as a person and student....

One the Best professor that i've had. Teaching style is excellent, very clear and concise. 202 is actually interesting when he teaches it. However if you are 10 seconds late to class ,either you step out or he steps out. If you move your head or scratch your back, you better leave the class. If you want to learn 202, take it with him.

Very difficult exams, but if you go to class and study you will have a great understanding of the material.

His teaching style needs improvement. When attempting to teach us new concepts, he applies them before fully explaining the fundamentals. Oh yea, taking tests without calculators teachs us nothing. Does anyone think everyone at Intel/AMD is doing nodal analysis with pen and paper?

Knows his stuff and teaches it well. Extremely low averages on exams (~40-45%). Not an easy class, but taught me a lot. Very helpful in office hours, even for other classes. Just don't show up late!

Difficult but good professor. Definitely do all the homework and do it again before exams. Exam questions are very close to homeworks. Lots of proofs. So practice them well.

Probably one of the best EE professors at Purdue, you will learn a lot if you follow his lectures.

The Best!

Good teacher, hard class.

How dare any of you complain about a professor like Ray Decarlo!! Obviously you must have had some amazing 201 teacher that doesnt exist anymore. People who claim Ray is a bad teacher are simply blaming the fact that the class is hard on him. Granted the jokes are a little stale, but hey he's a EE. Get used to it. You won't find a better 202 pro

Arguably the best professor Purdue's EE program has to offer. Unfortunately, DeCarlo often misinterprets the line between tough love and inhumane cruelty, with class policies that are masochistic and abusive. If you survive you will learn much, but expect borderline inhumane treatment from this Lord of the Laplace.

great teacher

He knows his stuff and can answer any question you have concerning the material from the course. That being said, he is also a major sadist, who enjoys torturing our young minds mentally. If you are a second late (I kid you not) you are thrown out. If your eyes wander a micrometer away from your sheet on an exam, he thinks you are cheating.

Can be a jerk at times, but also has a decent (if dry) sense of humor. Overall one of the best professors I have had.

I had this guy during the summer of 1987. I mostly remember that he constructed his multiple choice questions so that you had to do an incredible number of calculations to get the answer. I remember completing something like 400 3rd grade arthimetic operations in a very small time to get the right answer. Eeven worse - it was a simple concept.

I think he's really good and sarcastic in a funny way. I love going to his classes. He comes across as a very funny/impressive man.

...Absolutely amazing professor..Only willing to reward the hardworkers, and so others who complain should actually work harder, afterall no one ever said EE was gonna be easy.....By far, my favorite teacherat purdue.

He rips everyone, but its awesome until yourself gets ripped in half. But extremely entertaining to go to lecture. You have to have motivation cause he will give it to you.

He is a fun professor. Those who rate him low just because his 202 is very hard but that is unfair.

Great Teacher. pretty nice guy. Dark world of laplace! that's so fun

Awesome Prof! If you are an adult and can handle being responsible then this Prof is your best friend. Does everything he can to teach material in the clearest way, and if you put the effort in, the rewards are evident. Give respect and receive respect mentality, great class which keeps you interested!

His ECE602 is filled with excessive exams. Exams impossible to finish on time. Need to do a lot of hwk problems to finish the exams as much as possible. Gets really defensive when requiring a regrade. Do offer insights into the material. Excessive exams with limited time and no homework grading are not good ways to teach a 6-level graduate couse.

Great professor!

He is very strict. Be to class on time, don't use your cell phone in class, don't talk excessively/interrupt class. However if you don't upset him and respect him/his class, he is a very good professor and his exams and homeworks are very relevant to his lectures. Spent all my time in help room and I recommend that. You will learn a lot.

He is hilarious and I enjoyed his class too

Tough professor but the best I had in electrical engineering. He gives out handouts and believes in effort and practice. Do NOT be late or you won't get in.

knows what he is talking about, just do your work and pay attention. If you want to pass just show up

He is great, but study hard! If you don't like EE drop out now

If you didn't attend class you were more than likely not going to pass. He would always give quizzes in class, where you were allowed to ask everyone around you for help, so it was an easy A. Exams were doable if you understood the homework. The homework took forever though! He's my favorite professor at Purdue

Professor Decarlo definitely takes some getting used to. He prefers to teach the WHY more so that the HOW. This makes things like homework (which there is a ton of) and tests brutal. But at the end of the day I really felt like I had a solid grasp on the material. His classes are difficult but at the end of the day he is a superb professor.

He is really the best professor in ECE so far.

Best professor at Purdue! His tests are hard and he can be strict about technology in class and getting there late but his lectures are amazing. He is very clear and explains everything very well. He assigns long homeworks but they are very helpful when it comes to the test. Tests have difficult questions and are very hard to complete in time

He is the best professor you will have in your time here but it is also one of the hardest classes you will have.

This is the hardest class I have ever had. But, it was taught by the best professor I've ever had. Decarlo want's to see his students succeed, but the is no way in hell he's going to make it easy. If you have the option to not take this class, avoid the unnecessary stress. If you have to take this class, good luck.

Welcome to Dante's Inferno...

Extra help given if requested. Approachable and excellent manner. Knowledgeable and can teach undergrads and postgrads very well. Highly recommend any of his classes.

I would highly recommend him.

Best Professor at Purdue. Hands down the hardest class but also the most rewarding. I wish all professors were like him.

A stubborn but caring old guy, kinda strict but within the acceptable boundary. A respectful and an inspiring professor overall.

Dr. Decarlo is the definition of tough love; he wants you to succeed, but won't care if you fail. One of the best professors I've had here, but ECE202 is a terribly difficult and work heavy class. Put forth a serious effort, because if you don't, YOU WILL FAIL. Good luck.

Dr. DeCarlo is very strict. He doesn't tolerate tardiness, cell phones, or talking in class. And you can forget about negotiating your final grade. His homework takes lots of time and his tests are highly challenging. However, he is a stellar lecturer and does a fantastic job of explaining the material. He's also funny and tells silly stories.

Professor Decarlo is one of the rare few professors that warm up to students and regard them more than just students. Because of the difficulty of his class, I had problems coping and he gave me advice that really helped me to improve my study habits tremendously. I appreciate the difficulty of the class because it helped me to learn how to learn.

Definitely go to all classes because the in class quizzes are really easy if you pay attention. The exams are easy if you do a couple past exams. The homework actually helps you do well in the class. I learned so much in this class.

The best professor I have had so far at Purdue. His exams and homeworks are really tough. But it is absolutely worth. He teaches you not only the ECE material, but, surprisingly, patience and punctuality. Never be late to his class or have a cell phone out. You might hate it at first, but when you will look back, you'll appreciate him a lot.

Decarlo is probably the most interesting professor I've hard here my time at Purdue. He is a fantastic lecturer, explains concepts clearly, and speaks loudly and clearly, easily grabbing your attention. But this is at the cost of no phones/laptops. There was a LOT of homework, but definitely do it because it prepares for the test super well

He can be a friend or an enemy, your choice. If you give little effort, Ray can catch onto it and show little pity. But if you take the time and talk with him at office hours, you'll learn a lot and get to know a genuinely nice guy.

Best ECE professor in my opinion. Doesn't allow cellphones or coming late to class, but it doesn't matter because he was able to keep the class engaged. Too too much of homework but old exams were more or less similar to the current exam.

Get ready for your hardest class of your life. Explains extremely well and is very friendly and helpful. But don't ever not pay attention, he goes fast and gives TONS of homework even if you have an exam the same day. Oh and he also dresses up as Gandalf and screams YOU SHALL NOT PASS before the finals.
