Which of the following frequencies does not belong to FM broadcast.

Options

  1. A106   M H z
  2. B64   M H z
  3. C99   M H z
  4. D89   M H z

Correct answer

B. 64   M H z

Step-by-step solution

Sound waves of different frequencies can be used in different purposes. FM broadcasting frequently makes use of frequency modulation. Additionally, it is utilised in telemetry, radar, seismic prospecting, EEG-based seizure monitoring of neonates, two-way radio systems, sound synthesis, magnetic tape recording, and some video transmission systems. The range for FM broadcasting lies between 88   MHz to 108   MHz . Hence, 64   MHz does not belong to the FM broadcast.
