    What is the SNR in this ADC ?

    Finding SNR Hello, This equation is for an ADC: SNR = 6.02n + 1.76 dB , where n is the number of bits However, this equation has a few assumptions and is invalid if your input clips and saturates the ADC. Assuming my input signal does clip and has a guassian distribution, what is the...
