The Fourier series is a frequency-domain representation of a continuous-time periodic signal. What about aperiodic signals? The concept of Fourier series can be extended to the Fourier transform, ...
Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...
In this chapter, we go back to the study of discrete-time signals, this time focusing on the frequency domain. We will see that periodic discrete-time signals can be expanded in a finite Fourier sum ...
