Continuous-time Fourier Transform Problems Involving Cosine Signals

Two solved problems dealing with continuous-time Fourier transform and cosine signals, meant to help students brush up on their pre-requisite knowledge in a signal processing class. One of the problems corresponds to a simple cosine modulation problem. ------------------------------ Table of Contents ------------------------------ ** Problem 1--CTFT of a cosine signal 00:00 ** Problem 2--CTFT of a cosine modulated signal 07:34
