Student's Guide to Fourier, Laplace, and z Transcorms (Technical LAP Series Book 5)

A complete description of the four Fourier transforms; continuous-time transform and series, discrete-time transform and series. Power and energy spectrum. Insight into the relation between the Argand diagram (the complex plane) and the value of the transform at a particular frequency.
Laplace and z transforms with properties and applications with regions of convergence.
Sampling, multirate processing, and the FFT.
