Which of the following is a measure of the quality of an analog-to-digital converter?
- A.Total harmonic distortion (correct answer)
- B.Peak envelope power
- C.Reciprocal mixing
- D.Power factor
WhyTotal harmonic distortion is a measure of the quality of an analog-to-digital converter. Total harmonic distortion is a real measure of an analog-to-digital converter's quality, quantifying how much unwanted harmonic content the conversion process itself introduces into an otherwise clean input signal, answer A. Peak envelope power, reciprocal mixing, and power factor are all real concepts, but they're characteristics of transmitted signals or receivers, not measures of ADC conversion quality.
