السؤال 448

Which of the following is a type of analog-to-digital conversion?

  1. Successive approximationالإجابة الصحيحة
  2. Harmonic regeneration
  3. Level shifting
  4. Phase reversal

الشرح

A successive approximation converter compares the input against a trial voltage produced by an internal digital-to-analog converter, resolving one bit at a time from the most significant downward, so it is a standard analog-to-digital conversion architecture. Harmonic regeneration, level shifting and phase reversal are signal-processing operations that produce no digital output code.
