FM Radio Project Summary

In this project, we designed and implemented a simple FM radio system consisting of both a transmitter and a receiver.

The FM Transmitter modulates an audio input signal onto a high-frequency carrier wave using Frequency Modulation (FM). This allows the information signal to be transmitted wirelessly over a certain range.

The FM Receiver was built to demodulate the FM signal, recover the original audio, and play it through a connected output device (such as a speaker).

Proper tuning circuits were implemented using capacitors and inductors to select the desired frequency channel.

The project demonstrated the full communication process:

Signal Generation (audio input).

FM Transmission (modulation and carrier wave transmission).

FM Reception (demodulation and filtering).

Signal Output (recovered audio).

This project helped us understand the fundamental principles of wireless communication, including modulation, demodulation, and frequency tuning.
