Part IV
Entering the s- and z-Domains
Increase your understanding of working across domains by seeing how a continous-time filter can be taken to the discrete-time domain at www.dummies.com/extras/signalsandsystems.
In this part . . .
Generalize the Fourier transform to check out the s-domain for continuous-time signals and systems and the z-domain for the discrete-time counterpart.
Let the Laplace transform help you solve differential equations with friendly algebra.
See how to avoid the convolution integral by multiplying in the s- or z-domains and then returning to the time domain.
Find out how to work across domains and between continuous and discrete signals and systems to solve practical problems.
