Hi dear all:
it is because that periodical sampling would aliasing the high frequency noise into low frequency, so that the thermal noise should be integrated from 0 to unlimited high frequency, isn't it? But now my ADC is used in an image sensor and the sampling operation is not periodical. So:
(1)what is the proper integration frequency range of thermal noise?
(2)is the traditional periodical-sampling-and-doing-FFT method still proper in the SNR measurement of such an ADC?
thanks in advance!
