WitrynaTherefore, a Hermitian symmetric sequence ( x [ n] = x ∗ [ − n] for all n ) , which begins at n = − 4, and ends at n = 4, will lose this symmetry when interpreted in those programs. The effect is a shift of the signal to the right by 4 for your particular example. Hence, what you have compouted is not the FFT of the original symmetric ... WitrynaDear Sanjeev Kumar.
