E8A02
Which of the following is a type of analog-to-digital conversion?
- A.Successive approximation (correct answer)
- B.Harmonic regeneration
- C.Level shifting
- D.Phase reversal
WhySuccessive approximation is a type of analog-to-digital conversion. Successive approximation is a real type of analog-to-digital conversion, a technique that narrows in on the input voltage's digital equivalent one bit at a time through a series of comparisons, answer A. "Harmonic regeneration," "level shifting," and "phase reversal" aren't standard ADC conversion techniques.
