What is radio receiver circuit?
A radio receiver is connected to an antenna which converts some of the energy from the incoming radio wave into a tiny radio frequency AC voltage which is applied to the receiver’s input. An antenna typically consists of an arrangement of metal conductors.
What is FM receiver with block diagram?
The block diagram of an FM receiver is illustrated in Figure (a). The RF amplifier amplifies the received signal intercepted by the antenna. The amplified signal is then applied to the mixer stage. The second input of the mixer comes from the local oscillator.
How does a FM radio work?
In FM broadcasting, the frequency of the carrier wave is modulated to encode the sound. A radio receiver extracts the original program sound from the modulated radio signal and reproduces the sound in a loudspeaker. A commercial 35 kW FM radio transmitter built in the late 1980s.
How does a FM circuit work?
The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of the carrier wave according to the message signal.
How the FM signal is generated?
FM signals can be generated either by using direct frequency modulation, which is achieved by inputting a message directly into a voltage-controlled oscillator, or by using indirect frequency modulation, which is achieved by integrating a message signal to generate a phase-modulated signal, which is then used to …
What are the 5 main parts of a circuit?
The following common components are used in most printed circuit boards:
- Resistors. Resistors control the electric currents that pass through them, as well as the voltage in each component connected to them.
- Transistors.
- Capacitors.
- Inductors.
- Diodes.
How does FM radio circuit work?
FM Radio Circuit Principle: Radio is the reception of electromagnetic wave through air. The main principle of this circuit is to tune the circuit to the nearest frequency using the tank circuit. Data to be transmitted is frequency modulated at the transmission and is demodulated at the receiver side.
How does FM radio work simple?
How to make FM radio receiver at home?
The first step is to take the ribbon wire in the length of few inches longer than required.
How to build FM transmitter circuit?

How does an FM transmitter circuit work?
The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of the carrier wave according to the message signal. Generally, the FM transmitter uses VHF radio frequencies of 87.5 to 108.0 MHz to transmit & receive the FM signal.
