Kaz,
Thank you very much for your reply,
It is very helpful explaining how the conversion works but unfortunately is not what I am after.
I would like to know if there is any formula (mathematical relation) between output performance and bit growth.
Best Regards
George

I never heard of any formula for that. But my previous post tests that directly.
In practice we have to truncate signals to same width as input (usually). You choose your final ADC or DAC bitwidth and study accordingly.
There are formulas for SNR of quantisation noise at ADC/DAC which basically states that SNR = 6*bitwidth in dBs for a clean tone.
