![]() Emergency Broadcasting: FM transmitters can be used for emergency broadcasting, such as for public safety announcements or weather alerts.Audio Surveillance: FM transmitters can be used for covert audio surveillance by transmitting audio signals wirelessly to a nearby receiver.Remote Control: FM transmitters can be used to transmit signals wirelessly to remote control devices, such as model airplanes or drones.Wireless Headphones: FM transmitters can be used to transmit audio wirelessly to headphones or earbuds.Home Audio: FM transmitters can be used to transmit audio signals from a stereo system or other audio device to a nearby FM radio.Car Audio: FM transmitters can be used to transmit audio from portable music players or smartphones to car radios without the need for a wired connection.Wireless Microphones: FM transmitters can be used to transmit audio from a microphone wirelessly, making it ideal for public speaking, performances, and broadcasting.FM Radio Broadcasting: FM transmitters are commonly used by radio stations to transmit their signals to listeners.Make connections according to the circuit diagram given below.įM transmitter circuits can be used in a variety of applications, including: You will require the following hardware for FM Transmitter Circuit Components In many countries, the use of FM transmitters without a license is illegal. It is important to note that the use of FM transmitters is regulated by local laws and regulations. The circuit can be powered by batteries or an external power supply. The modulated signal is then amplified and transmitted through the antenna.įM transmitter circuits can be built using discrete components such as transistors and capacitors, or can be built using integrated circuits (ICs) specifically designed for FM transmission. The input signal is fed into the frequency modulator, which varies the frequency of the oscillator. The input signal to the FM transmitter circuit can come from a variety of sources such as a microphone, CD player, or computer. Antenna: This is used to transmit the signal wirelessly.Amplifier: This amplifies the signal generated by the frequency modulator to a level that is strong enough to be transmitted.The frequency of the oscillator changes in proportion to the amplitude of the input signal. Frequency Modulator: This modulates the frequency of the oscillator based on the input signal.The oscillator frequency is typically in the range of 88 MHz to 108 MHz for FM radio transmission. ![]() In FM, the frequency of the signal is varied based on the input signal.
