Two quick PFB/FFT questions. 1) The bin width scaling parameter in PFB_FIR. Can someone explain how this works? If you increase the bin width, doesn't the output rate of the PFB need to increase? Does a value of 2 here make the bins twice as wide as a PFB with bins that are "normally" spaced?
2) We are feeding the CASPER FFT complex data with 2^N points. The output is complex data with 2^(N-1) points. Where did my negative frequencies go? Since the input is complex the negative frequencies are independent of the positive freqs, and I need them! Thanks, Ben
