Let h
and g be two different real sequences. Form the complex sequence:
x=h+jg
Finding the FFT of x, we can find the FFTs of h and g. First, show analytically how the H(k) and G(k) are found from X(k). Second let h and g be as below
h=exp(-n)
g=cos((2*pi*n)/256)
0<=n<256
Use the results analytically obtained to calculate the FFTs of h and g. Plot abs(H(k))
and abs(G(k))
