Parseval theorem, Mathematics

Assignment Help:

Verify the Parseval theorem for the discrete-time signal x(n) and its DFT from given equations.

Compute the linear convolution of the discrete-time signal x(n) ={3, 2, 2,1} and the impulse response function of a filter h(n) = {2, 1, 3} using the DFT and the IDFT.
