Abstract

Basic signals, their classifications and shifting and scaling of signals are reviewed. First, basic signals such as impulse, sinusoid, step, ramp, and exponential are introduced. Then, the classification of signals, based on periodicity, sampling along the time and amplitude scales, even and odd symmetries, power and energy and randomness are presented. Signal operations shifting and scaling are then explored. Finally, a review of the complex number system concludes the chapter.
