Complete ADC SNR formula when signal is not full scale
I am very in pain to find a (any) paper giving more than the traditional SNR for full-scale wave sampled by ADC
$$ SNR(Full Scale Waveform) = 6.02N + 1.76 (dB)$$
As far as I can remember if the signal ...

The relationship between bit depth and SNR in ADC
An 8-bit audio signal has a theoretical maximum SNR of 48.16 dB (20log(2^8)).
My question then would be, does this work in reverse, i.e. would an analogue audio (or video) signal with an SNR of <=...

Does SNR improve at higher sampling rates for a low pass filtered signal?
Let's say we want to extract 1Hz signal from a noisy signal by using a LPF.
And assume we have sampled it with 100Hz sampling rate.
If we would have sampled it with 1kHz sampling rate and use the ...

How do you find the resolution and sampling rate needed for a certain signal to noise ratio of an analog to digital converter?
For example, I want to convert an analog voltage signal to digital. I want to have a signal to noise ratio of at least 50,000 without aliasing. What sampling rate and resolution could I use to achieve ...
