What are the parts of a radio receiver?

Today’s radio consists of an antenna, printed circuit board, resistors, capacitors, coils and transformers, transistors, integrated circuits, and a speaker. All of these parts are housed in a plastic case. An internal antenna consists of small-diameter insulated copper wire wound around a ferrite core.

How do FM receivers work?

The receiver uses electronic filters to separate the desired signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Of the radio waves, FM is the most popular one.

What are the main components block of FM receivers?

FM Receiver Block Diagram Explained

  • RF amplifier. The rf amplifier receives the desired signal from the antenna and provides tuning to remove the image signal alongside all unwanted signals on other frequencies.
  • Mixer.
  • IF amplifier and Filter.
  • Demodulator.
  • Audio amplifier.

What are the parts of radio receiver and function?

In the simplest type of radio receiver, called a tuned radio frequency (TRF) receiver, the three functions above are performed consecutively: (1) the mix of radio signals from the antenna is filtered to extract the signal of the desired transmitter; (2) this oscillating voltage is sent through a radio frequency (RF) …

What is a circuit component?

Ans: A component is explained as any device which is in an electric circuit. that transfers the energy of electrical power into another form. A diode, lamp, motor, LDR, resistor and a thermistor are all such examples of electrical components.

What is radio circuit?

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.

What is a modulation circuit?

A modulator is a circuit that combines two different signals in such a way that they can be pulled apart later and the information obtained.

Why ferrite core is used in radio receivers?

In the coil, a low-loss, high-magnetic-permeability ferrite core is used that is stable against thermal fluctuation. The system can receive weak radio waves and can be used for several years without battery replacement because a small but high-performance ferrite core is used.

What makes a good radio receiver?

RADIOS: For good reception, a radio must have good selectivity (selectivity is a radio’s ability to separate weak stations located nearby, on the FM dial, strong stations) and good sensitivity (the ability to receive weak, distant, stations at all!)
