Question

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

• A. $64 \,MHz$
• B. $106 \,MHz$
• C. $99\, MHz$
• D. $89 \,MHz$

Answer 1

Answer: (A)

$64 \,MHz$

Answer 2

The range of $88\ MHz$ to $108\ MHz$ is chosen for FM broadcasting because it provides a wide range of frequencies that can carry a diverse range of audio content while avoiding interference with other radio services operating in different frequency bands. This frequency range also allows for a reasonable balance between signal coverage and bandwidth utilization.
Then, the frequency that does not belong to FM broadcast is $64\ MHz$ because it falls outside the typical FM broadcast frequency range.

So, the correct option is (A): $64\ MHz$
