Question

What is the best frequency for FM transmitters?

Answer 1

Hint: A transmitter and receiver are components of every communication system, and the transmitter sends the signal as waves such that the waves being sent have a certain frequency. And the signal with a certain frequency is likewise picked up by the receiver.

Complete step by step solution:
An electronic device known as a radio or FM receiver receives radio waves or signals and transforms the data they carry into a form that may be used. To receive the necessary frequency waves or signals and transform them into information, an antenna is utilised.

The necessary frequency waves or signals will be separated from the other signals using an electrical filter. An electronic amplifier is used to increase the power and the strength of the signal for the next process and finally gets the required information through the demodulation in the receiver.

The most often used radio wave modulation is frequency modulation. The radio waves are frequently broadcast via frequency modulation. Additionally, it is frequently used in telephony, RADAR, multi-way radio systems, musical instruments, magnetic recording systems, and some visual transmission systems, as well as for monitoring newborn babies using electroencephalograms.

The carrier wave frequency is equivalent to the audio signal of the amplitude and the FM transmitter to produce a VHF band of \[88\] to \[108MHz\].

Therefore, the frequency range best for FM transmission is \[88-108{\text{ }}MHz\] band, this is the frequency range at which all the broadcast radio works.

Note: The radio frequency (RF) amplifier picks up the radio waves or signals and sends them to the mixer, which then sends the signal or waves to the filter, where the required frequency of the wave or signal is separated and given to the demodulator, where it is transformed into audio data.
