(1) because the general approach is to give about 80% effective bandwidth due to the fact that filters cannot have infinitely steep edges.
(2) complex baseband sampling. Sample rate == bandwidth. Sent from my iPhone > On May 11, 2021, at 6:15 PM, isaac mario tupac davila <[email protected]> > wrote: > > > Hello community > > I'm Isaac.
