What I knew: The ADC resolution selection depends on the ADC inherent noise and input signal SNR.
Our application: Very high precision measurement of signals ranging 1kHz to 10kHz. We want to get as accurate result as possible, even 24-bit result.
The above statement, however, does not take digital signal processing after ADC sampling into consideration.
Since DSP techniques such as FIR, FFT and etc. may reduce the noises greatly, is it possible that increasing ADC resolution may also improve the measurement result when taking DSP techniques into consideration?
