Hello
I have built a lower-bit quantization scheme in the rx_bufffer.v using
4-bit samples, storing one byte for each clock sample (for both I and Q)
and then filling up the 16-bit FIFO with another 8 bit value coming from
the next clock sample.
Whan I did some tests and plotted the results everything looked fine,
like frequency and sahpe of the waveform, I could see though some spikes
equal to a value of 1. This is coming from the rounding effect which I
have not removed. When I do remove that then the spikes become more (in
population not in amplitude) and then I had a look and I saw in the list
that there is a DC offset that causes that?
Can anyone advice me how to get rid of these spikes?
Thank you
Rigas
