What is Discrete Fourier Analysis of Signals about?
The document introduces discrete time periodic signals and their Fourier analysis. It defines periodic signals as signals that repeat over time with a finite period. The Discrete Fourier Series (DFS) provides an expansion of periodic signals in terms of complex exponentials or sinusoids. Any periodic signal with period N can be written as a sum of N complex exponentials with the same period N. This representation provides the frequency domain view of periodic signals and their frequency components.
