Sampling and Reconstruction - Ptolemy Project

The frequency domain analysis of the previous chapters relied heavily on complex exponential signals. Recall that a cosine can be given as a sum of two complex exponentials, using Euler’s relation, cos(2p. ft)=0: 5(e. i. 2p. ft + e ¡i. 2p. ft): One of the complex exponentials is at frequency. f, an the other is at frequency ¡f.
