DSP

(1) The spectrum estimated by DFT requires the corresponding waveform to be drawn.

(2) When L = 1024, the time required for linear convolution and fast convolution is calculated and compared with that for linear convolution of two sequences by overlapping addition method.

(3) Judging whether two spectral peaks can be distinguished by zero-filling method; if not, what method should be adopted to distinguish two spectral peaks?
