Abstract :
We consider here the problem of selecting the lowpass sampling bandwidth for a digital mechanization of a matchedfilter bit-synchronizer combination. In particular, if digital data at a rate 
bits/second plus Gaussian noise is passed through a filter of bandwidth 
and then sampled at the Nyquist rate, i.e., 
, then how small can we choose 
without paying an appreciable penalty in the SNR performance of the data detector?
