Which of the following is a measure of the quality of an analog-to-digital converter?
Why An analog-to-digital converter is judged by how faithfully its digital output reproduces the input waveform, so the standard figures of merit are distortion and noise numbers: total harmonic distortion, signal-to-noise ratio, SINAD, and effective number of bits. Quantization error and any nonlinearity in the converter's transfer curve create spurious products at harmonics of a pure input tone, and total harmonic distortion sums the power in those harmonics relative to the fundamental. A lower THD figure means the converter's steps track the analog input more linearly.
Watch out Peak envelope power is a transmitter output measurement, reciprocal mixing describes receiver local-oscillator phase noise mixing strong adjacent signals into the passband, and power factor applies to AC circuits with reactive loads. None of them says anything about digitizing accuracy.
ADC quality = how clean the digitized tone is: THD, SNR, SINAD, ENOB. The other three choices belong to transmitters, receivers and AC power.
