HI kaz

In the pulse shaping, root raised cosine

h = firrcos(50,.25,.15,1,'rolloff','sqrt');

Can u explain me why 0.25 and 1 are taken in the RRC function which represent cutoff and sampling

as

Fs = 100; %MHz, IF sampling frequency

Fc = 20; %MHz, upconverter frequency

Fc/Fs = 20/100 = 0.2

so can i use

h = firrcos(50,.2,.15,1,'rolloff','sqrt');
