"The book begins with mathematical methods for describing signals and systems, in both continuous and discrete time. I introduce the idea of a transform with, the Fourier series, and from that base move to the Fourier transform as an extension of the Fourier series to aperiodic signals. There is a chapter on applications of Fourier analysis, including filters and communication systems. After covering Fourier methods, I use them in explaining the implications of sampling and in the analysis of the correlation between two signals and the energy and power spectral density of signals. I introduce the Laplace transform both as a generalization of the continuous-time Fourier transform for unbounded signals and unstable systems and as a powerful tool in system analysis because of its very close association with the eigenvalues and eigenfunctions of continuous-time linear systems. Then I present applications of the Laplace transform in circuit analysis, feedback systems, and multiple-input,...
