All,Randy and I are working on a low resolution version of our GUPPi DSP designs. Basically, we want to take our existing (and widely used) 2048 channel design and reduce it to 128 channels, for the sake of faster readout times. We did this by simply changing the mask parameters of the PFB and FFT blocks to give us 128 channels. This seems like a very simple thing but with the 128 channel design, we are getting bad spectra.
Does anyone have any thoughts on this? Thanks, Jason
