when calculating the SNR of adc,should the bandwidth of noise be 1/2fsample?
when calculating the SNR of adc,if i want to calculate all the noise,should the bandwidth of noise be 1/2fsample?in the book,its said that the quantization noise of adc is distributed in the range from zero to 1/2fsample.and i have another question.when calculating the noise of a sigma delta adc from the output of its digital filter,should the integration bandwidth of noise be set to 0 to 1/2 of the clock frequency of the output digital code?
