The signal we wanted was at 1420.4 MHz. The downconverter they had
there had a 1320 MHz LO. That put the H line at 100.4 MHz. Since the

The DDC was set to -5.75Mhz. Doesn't the TVRX produce a 5.75Mhz IF?

Just curious, how much logic does each DDC (cordic, CIC, decimator)
require? I'm trying to estimate how many would fit in an XC3S400. I
think that currently the code uses the "free cordic multiply" with a
cordic for each channel. Could we instead take the sin and cos off of a
single cordic and u

Hi,
In the process of demodulating the video sigal from the tv signal we receive, we
have been interpolating from 8 MS/s by a factor of 2 to 16 MS/s. However, just
demodulating the audio alone takes 97% of our computer's usage, and as soon as
we interpolate to 16 MS/s the usage peaks at 100% and

It is not. Matt sent the file to me after he sent the DBS_RX for my GPS

prototype transponder plans needed a platform. He sent the file saying
"Ooops, you need this".

What's different in the new fpga stuff for DBS_RX? Hmm, I guess I have to
recursive diff usrp-0.8 against the CVS, assuming the
