| Abstract: |
In Chapter 9, we define the Discrete Fourier Transform (DFT), by sampling in the frequency domain, and the circular symmetries of a sequence. Then, we prove the following properties of DFT: periodicity, linearity, cyclic convolution, time-reversal property, cyclic shift in the time domain, and cyclic shift in the frequency domain. Finally, we present how DFT can be used for the calculation of the output of a linear filter.
