What is the principle of an FM 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.
How do you set up an FM radio?
To operate the FM Radio circuit following steps are to be followed: Initially connect the circuit as shown in the figure. Connect the power supply to the circuit. Now press the switch. Now adjust the frequency of the circuit by varying the trim pot (variable capacitor) of the tank circuit.
How many cycles per second does a FM radio transmitter generate?
FM radio signals are operating in the range of 100,000,000 hertz, so 101.5 on the FM dial is a transmitter generating a sine wave at 101,500,000 cycles per second. See How the Radio Spectrum Works for details. Here’s a real world example.
How does a radio transmitter transmit a message?
The transmitter takes some sort of message (it could be the sound of someone’s voice, pictures for a TV set, data for a radio modem or whatever), encodes it onto a sine wave and transmits it with radio waves. The receiver receives the radio waves and decodes the message from the sine wave it receives.
