Circuit Diagram Of Am Fm Radio

By | October 9, 2017



Amplitude Modulation (AM) and Frequency Modulation (FM) radio have been powering households for almost a century; these two forms of radio broadcasting are still popular today. Both AM and FM use electronic circuits to create a signal that can be transmitted and received by radios. To understand how both methods of broadcasting work, it's important to understand the circuit diagram of an AM/FM radio.

The basic components of an AM/FM radio are the circuit boards, transistors, resistors, and diodes. The transistors and resistors control the frequency and amplitude of the signal, while the diodes regulate the direction of the current flow. A power supply is needed to provide the necessary voltage and current to operate the device.

Once all of the components are in place, the next step is to add a tuner to the circuit. This is done by connecting a wire antenna to the circuit, which allows the radio to receive broadcasts at different frequencies. The tuner can then be adjusted to tune in a specific AM or FM station.

Once the tuner is in place and the desired station is tuned in, the signal can then be amplified. This is done with an amplifier, which can boost the signal strength to make it audible over a loudspeaker.

Finally, the signal passes through a demodulator. This circuit takes the signal and converts it back into audio form. The resulting sound is then sent to the speakers, allowing listeners to enjoy the sound of AM and FM radio.

By understanding the circuit diagram of an AM/FM radio, it's possible to understand how the device works to create audio. This understanding can then be used to build or modify the set to suit individual requirements. Whether you are looking for improved performance or just a different look, the components found in this circuit diagram can help give you the sound you're looking for.
