Which of the following frequencies does not belong to FM broadcast?
- $64 \,MHz$
- $106 \,MHz$
- $99\, MHz$
- $89 \,MHz$
The Correct Option is A
Approach Solution - 1
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): \(64\ MHz\)
Approach Solution -2
FM broadcast range is 88 MHz to 108 MHz. Since 64 MHz falls outside this range, it is the correct answer.

Communication Systems
A system that describes the information exchange between two points is called the communication system. The transmission and reception process of information is called communication. The major elements of communication are such as:
- The Transmitter of information
- Channel or medium of communication
- The Receiver of information
Examples Of Communication Systems:
The following are the examples of communication systems:
- Internet
- Public Switched Telephone network
- Intranet and Extranet
- Television
Types Of Communication Systems:
Turning on Signal specification or technology, the communication system is categorized as follows:
- Analog technology communicates data as electronic signals of differing frequencies or amplitude. For instance Broadcast and telephone transmission.
- In Digital technology, the data are created and processed in two states: High (represented as 1) and Low (represented as 0). Also this technology stores and transmits data in the form of 1's and 0's.
