"SIGNALS AND SYSTEMS: AN ENGINEERING PERSPECTIVE by Burton" explores the study of signals, which are functions conveying information about phenomena, within the field of electrical engineering. It encompasses the analysis and mathematical representation of input and output signals across four main domains: frequency, time, sss, and zzz. Signal processing involves analyzing, synthesizing, and modifying signals to enhance efficiency and transmission quality. Systems, comprising physical components with inputs and outputs, are integral to this study. The book classifies signals based on various criteria, including analog, digital, deterministic, random, energy, and power types.
