Re: [Discuss-gnuradio] AGC and Dynamic Range of ADC

Well that is 80 dB of dynamic range inside the Nyquist zone (at best and let's call it N). I can add a "bit" of increase in dynamic range by downsampling (filter and decimation) and growing the accumulator size by a bit for each decimation by 4. This will increase dynamic range. I don't believe

I have USRPN210 with WBX and RFX2400. Is there any AGC chip on N210 motherboard or WBX, RFX2400 before ADC to utilize the dynamic range of ADC ? if yes, which one? If not, then won't the varying input signal (for example signal from moving object) to ADC affect the performance of ADC ? Bob __
