Signal Processing: Theory, Analysis, and Applications

الملخص

This book introduces the fundamentals of signal processing by presenting signals in time and frequency domains and explaining how information-bearing signals are manipulated, detected, and interpreted. It covers core operations such as convolution, correlation, and sampling, then develops spectral tools including Fourier series/transform, the DFT/FFT, and the z-transform. The text also treats analog and digital filtering, including the design and application of FIR and IIR filters, with reinforcement exercises and engineering-oriented applications.
