Instead of demonstrating how 16x oversampling can add two bits of resolution to your 10-bit ADC, it’s a lot clearer with the one-bit example. [Paul’s] demo is great because it makes a strange ...

A 16-bit ADC, then, should have 98 dB of SNR. If the actual SNR is 89, the ADC has 14.5 effective bits. Any time the SNR ACTUAL is 6 dB less than SNR IDEAL , there is at least a bit of noise added ...
