1) pfb_fir_frontend() - fixed summation to give the correct number of time chunks (was short by 1) 2) pfb_filterbank() - trim 'x' to ensure an integer number of windows fit 3) pfb_spectrometer() - added code to normalize the PFB by its processing gain 4) pfb_spectrometer() - replaced duplicated code with a call to pfb_filterbank()
