Hi All

I am testing dynamic spec of pipeline ADC such as SNR, ENOB. I use window sampling method to measure frequency domain. however, by using different window( hanning, hamming, backham,) the noise floors are diffierent.

Does anyone know how to calcaculate noise floor in these cases? And which window is better?
