Pros: Relatively easy quizzes and midterms
Cons: Inexplainably bad attitude to students. Has a "get out of my face" attitude to all students.
I want to preface, I'm doing well in the class, and not just a salty and spiteful student.
I wrote this review because for Circuits, there are two teachers - Gerber and Hrebien. Both are terrible, so if you're taking this class, there's really no lesser of the two evils, both are terrible. If you need to take this class - I'm sorry, but you need to brave through this. For Hrebien, I've never seen a teacher despise and hate his students so much. His attitude is unacceptable. He treats your questions with mocking and condescension, so if you're the type of student that needs to ask questions, whether it be in private one-on-one in office or in-class (God forbid you), prepare to be mocked. Hrebien is a low-grade teacher, with the only good thing about this class being his quizzes and midterms being fairly easy. I hope making students feel like shit for asking questions helps you sleep at night Hrebien.

Pros: Weekly hw is extra credit and helpful
Cons: extremely boring
This professor is extremely boring and often condescending when answering questions. Weekly quizzes are easy grades if you know what you're doing. Weekly homework is not mandatory but is 5% extra credit if you're willing to put in the effort. He drops the two lowest quiz grades. You're supposed to read the textbook, but very few people do.

Pros: He is easy to understand
Cons: He can be rude when students ask questions or don't fully understand the material. He also assigns an unnecessary amount of homework and the problems can be overly complicated while it is the fundamentals that need to be learned here. The questions on the quizzes and exams are easy in comparison to homework problems but the homework is so hard that it takes away from learning the basics when making a bunch of tedious math errors

Pros: He gives you all of his notes, you just have to pay attention and fill some things in.
Cons: Weekly Quizzes are kind of hard.

Pros: 1)Explains the concepts very well
2)Ensures all students understand the concept before moving onto the next topic
3)Is to the point and is able to stick to the most important and relevant information
4)HW's, quizes, midterms and finals are similar, if you understand what you are doing you will do well in the exam.
5) doing the hw and some little more practise is good enough for exam
Cons: 1) Slightly grouchy, or easily irritable
2) might get a little annoyed if you ask too many questions or questions on basic things-However note he will still explain everything to you and answer your questions
Great professor. I liked him. He might not be the most inspiring professor (i.e he might not inspire you to become the next graham bell or see EE in a new light or something) but in terms of purely teaching the course and teaching it well and explaining the concepts to you he is great. Take him if you can.

Pros: Great professor to have. Understands the student's questions and explains them pretty well. Always takes interest in students and is sure we understand stuff. He is quick and good in his explanation. The division of 3 hour class is systematic.
Cons: A 3 hour class a week is too long. It would be better if it is divided among 2 days a week.
Consider taking !!

Doctor Hrebien is a very good professor. He explains material in a very clear manner and would no proceed if you say you did not understand it.
However, He might get a bit agitated if you ask questions . Anyhow even with a frown he does answer the question very clearly.
I would retake him.
Got to say ECE 200 is a hard course but if you really work hard on it you can get a A.
His quizes and midterms are moderate. If you do the homework its pretty straightforward. If not its hard.

Hard class in general but at least he goes through every thing and actually teaches. Much better than the alternative, but the computer portion was ridiculous.

He is so boring. Instead of teaching, he only read the over-head slides. Also, the word terms used in the slides is even more confusing and difficult to read than the text book. The grading is hard.

Hrebien's classes are somewhat dull, but he is a very good teacher as long as you can make yourself pay attention. He's good at breaking things down and explaining them. True sometimes it gets repetitive and boring, but I'd rather have that than someone who doesn't want to waste his time teaching the concepts. I don't agree with people who say he doesn't care about his students; I just think he wants to be respected, and the times I've heard him give students a hard time they pretty much deserved it...

Fact: this guy does not give a shit about you and will be a total jerk if you ever approach him. However, if you show up to class and actually listen and not act like you're too good for Differential Equations, this is the easiest fucking class EVER.
He teaches the material so damn well. There are at least 3 old quizzes posted online for each quiz you have to take, you can have a calculator and four pages of notes and a Schaum's outline for god's sake. There is NO EXCUSE to not have an A in this class. If you don't get an A, it is because you are a complete idiot and probably should have spent less time hung over and more time in class.

I think I'm in the minority here, but I actually really like Systems I, and I think he's a great teacher for it. He does go slow, that is true, but it's for you to better understand him. It's not a riveting class, but I find that if you can just pay attention, it does go by quickly. He's not very friendly if you ask him a question, but TA's are pretty friendly if you e-mail them. They DO grade hard though. Find somebody else's old homework, and spend several hours a week on Systems. Old quizzes are posted online. An A is more than manageable.

This guy takes forever to cover topics. At least Jim Donnelly would jump around and hoot and holler now and again. During the hour of his lecture, it will be a feat of human endurance to pay attention to his monotone dronings about modeling.
His TAs grade hard and he's not too lenient on homework. Fortunately, by the time you get to the final (50% of your grade, by the way), you should know just by reading the book to get a C in the class.
Take solace in knowing tDEC ends in one more term after this class.

I attended a portion of his first class and never returned. He just outlined the text. I found it better to just do that myself and at least learn it all the way through. If you did well in Systems 1, you should be able to not go to his lectures and teach yourself the rest.

The guy does care and wants you to learn. Even has tips so you don't have to do stuff the hard way. Takes some getting used to but once u check it with the hard way things become easier.
