Hello again, One other question: Is there a relation between the taps of the PFB FIR and the number of input streams to the FFT_Biplex module ?
Size of PFB: (2?)PFBSizeThe number of channels in the PFB (this should also be the size of the FFT which follows).Total Number of Taps:TotalTapsThe number of taps in the PFB FIR filter. Each tap uses 2 real multiplier cores and requires buffering the real and imaginary streams for 2*P**F**B**S**i* *z**e* samples.Windowing FunctionWindowTypeWhich windowing function to use (this allows trading passband ripple for steepness of rolloff, etc).Number of Simultaneous Inputs: (2?)n_inputsThe number of parallel time samples which are presented to the FFT core each clock. The number of output ports are set to this same value. >From the above tab in the blockumentation I see that *number of simultaneous inputs* is the parallel time samples presented to the fft core. Does this mean say, I have a 16384 PFB size, setting the taps as two, this would give me 2 8192 sample streams, so now, will these 2 8192 sample streams be the input of the subsequent FFT core ? I.e the number of inputs must be 1 and the number of input streams must be 2 ? Kindly clarify !
