Signals and Systems
Bucholz was super helpful and engaging by making a lot of students do in class work (from assigning people to make graphs to trivia contests for extra credit). She does an amazing job of making any concept interesting.
Really math heavy class. Learned about Fourier series, Fourier transform, sampling, and the Laplace transform - so essentially if you liked Math 216 you will enjoy the class. Tough exams but overall average class.
