Abstract: |
Chapter 3 focuses on sinusoidal signals, defines the concepts of frequency and period, and studies the conditions for periodicity of sums of periodic signals. The concept of frequency is closely related to a specific type of periodic motion called harmonic oscillation and is described by sinusoidal functions. Then, we define harmonically related signals and study the sampling of sinusoidal signals. Frequency has the dimension of inverse time. Therefore, we expect that the nature of (continuous or discrete) time will affect the nature of frequency, respectively. We present the concepts in the reverse order of that of Chapters 1 and 2. We begin with continuous-time sinusoidal signals and continue with discrete-time sinusoidal signals.
