In FM, the effect of noise is more on higher frequencies when compared with low frequencies. Therefore in order to have high signal-to-noise ratio(low noise), the high frequencies are amplified at the transmitter side and for compensation deemphasis(decreasing the amplitude of those boosted frequencies ) is done at receiver.

Why preemphasis circuits are used?

Preemphasis circuits are used to enhance the transmission quality of audio signals by boosting higher frequency components before transmission. This compensates for frequency-dependent losses in the communication medium, allowing for clearer reproduction of sound. By increasing the amplitude of higher frequencies, preemphasis helps to reduce distortion and improve signal-to-noise ratios, particularly in systems like FM broadcasting and audio recording. Ultimately, it ensures a more faithful representation of the original audio signal upon playback.

What is FM transmitter and what are the different FM transmitters?

FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
