Introduction to Circular Convolution and Filtering with the DFT
Relates the DTFT convolution-multiplication property to the DFT and the conditions under which multiplication of DFT coefficients corresponds to convolution in the time domain. Introduction to filtering by multiplication of DFT coefficients.
