Yes, it's so easy it does feel like cheating sometimes. Doesn't work well for non-homogeneous equations though, because you might end up with an expression in frequency that doesn't have an easily found inverse transform.

>Heh, same, now I'm dying in a class that uses it.
Yeah, that'll probably happen once I start taking the required electronics design courses. Op amps I don't really get, and although I understand filters pretty intuitively, I don't get how inductors or capacitors have filtering qualities outside of the "mass" argument (but that doesn't tell me how to design a lowpass filter using circuit elements).

>Is there any signal processing textbook/resource you'd recommend?
For beginners, Oppenheim "Signals & Systems" is a good introductory text. It goes through convolution, defining LTI systems, Fourier series, Fourier transforms (continuous and discrete time), Laplace & Z transforms, and a little taste of feedback systems at the end to get you interested in controls. If you want something a little more hardcore, you could go Oppenheim "Discrete Signal Processing," but that one (understandably) doesn't really do continuous time stuff. Dunno about online resources.
