Re: [Discuss-gnuradio] SNR Peak AMplitude and Noise Floor Calculation

2014-09-26 Thread Jeff Long
Ankit, First, calibration is outside the scope (so to speak) of GNU Radio and USRPs, so absolute measurements are going to require test equipment. But, you can determine SNR and the peak amplitude above the noise floor for some simple signals by viewing them on uhd_fft or a similar program.

Bob, Saw this the other day, but there isn't a lot to go on here. If block2 is your own, you can make it do the bypass. You can also use some of the logic blocks and a multiplier depending on what you're doing. There isn't really a concept of on-the-fly switching in GNU Radio. - Jeff On 09/
