Re: [Discuss-gnuradio] How to use the rx_decim and interp.

[srinivas naga vutukuri]

Yes, now correctly calling those two members, got 100M on ADC and DAC. 
But when i use interp = 4 and rx_decim = 4 what ever input samples 
tranmsitting is not correctly coming out? Any thought on this?


best regards,
srinivas.
