Q. Which of the following FM demodulator is sometimes known as pulse averaging discriminator?

  • (A) slope detection
  • (B) zero crossing detection
  • (C) quadrature detection
  • (D) phase locked discriminator

Explanation by: Admin

zero crossing detector is sometimes known as pulse averaging discriminator. the rationale behind this technique is to use the output of the zero crossing detector to generate a pulse train with an average value that is proportional to frequency of the input signal.
