What is amplitude in ADC?
The resolution of the ADC is the number of bits it uses to digitize the input samples. The amplitude resolution specification is usually expressed as a number of bits; for instance, 8-bits or 16-bits. A digitizer with 8-bits of amplitude resolution breaks the digitizer's input amplitude range into 28 or 256 levels.
How do you find the amplitude and phase of a signal?
As for the amplitudes you can get them directly by calculating the peak values of the sine waves. Afterwards you can calculate the phase angle phi= phi2-phi1 and the ratio of the magnitudes between B/A. All you need is to display the waveforms in same diagram.
