real valued fft
I have one query about DFT.
In DFT, when input is real, we get even symmetry magnitude spectrum.
It means that if we perform N-point DFT on a real input sequence, we'll get N separate complex DFT output terms but first (N/2 + 1) terms are independent.
Why one term is more instead of N/2 terms?
Please clarify my confusion.
Thanks and regards,
Naresh
