17 years agoContinuing with my question on interpreting the FFT output...
May be the observation that I described in my previous post has something to do with my initial question several posts ago, i.e., the amplitudes fluctuate constantly with a constant input. Because I am only looking at the source_exp and source_real FFT outputs, and ignoring the source_imag output, therefore, in every 64th cycle, source_real goes to 0. And for the other cycles, source_real decreases between the max and 0? Do you thing this is the reason?
