Hi all,
I happen to see this expression for Average FFT noise floor in many Application Notes. ---------- Average FFT Noise Floor (dB) = 6.02n + 1.76dB + 10 log(3*M / (pi * ENBW)), where M is the number of data points in the FFT. ENBW is the equivalent noise bandwidth of the window function (see next section on how FFTs are generated) n is the number of bits of the A/D converter ----------
Please help me in finding a reference for deriving this expression.
Thanks, yvkrishna
