Question 457

Which of the following is a measure of the quality of an analog-to-digital converter?

  1. Total harmonic distortionBonne réponse
  2. Peak envelope power
  3. Reciprocal mixing
  4. Power factor

Explication

Passing a clean sine wave through the converter and measuring the harmonic products in the digitized result exposes non-linearity, unequal step sizes and missing codes, so total harmonic distortion is a standard figure of merit for converters. Peak envelope power, reciprocal mixing and power factor describe transmitters, receivers and AC loads instead.
