Signals and Transforms

  • Lars WanhammarEmail author

In this chapter, we discuss analog and digital signals and the corresponding Fourier transform and the z-transform as well as some fundamental properties of these transforms. We also discuss sampling of analog signals, the sampling theorem, aliasing, Poisson’s sum formula, and analog-to-digital and digital-to analog converters.
