Raised Cosine Filter design

GNU Radio

Hi,
I want a raised cosine filter for the transmitter and can someone lead
me to
a place where I can develop one similar to what we have in gr_firdes.h

Thanks

Look at the source code used to generate the raised cosine, gr_firdes.h
should point to it. Making your own should follow directly from that;
also
the wikipedia page on the raised cosine is also nice.

Its not black magic, so do not fear the source. :stuck_out_tongue:

That is the best source currently in my opinion especially his
discussion of
HOW BAD RAISED COSINE FILTERS ARE AS NYQUIST FILTERS FOR DATA
TRANSMISSION.
