I think that since in the scenario you are describing there is all
virtual there is no ADC but the round aproximation from the cos(t)
function to a fixed number of bits used to represent the number with a
float the computer is using, so the noise you can see in the FFT is the
is indeed a quantizat
There's no ADC involved! This is DSP! I can't really pinpoint it, but
you have some misconception about what GNU Radio is. It's software. An
ADC is a piece of hardware.
That's simply the floating point quantization error, numerical stability
of the FFT, the absolute value and the averaging operati

Hi.
