Overview

This experiment demonstrates a frequency modulation (FM) circuit, where the frequency of a signal is varied according to an input signal.

Components Required

• Oscillator circuit
• Modulating signal (e.g., audio signal)
• Resistors
• Capacitors
• Power supply
• Breadboard and wires

Procedure

1. Generate a carrier signal and apply the modulating signal to the oscillator circuit.

2. Observe the frequency variations of the carrier signal based on the modulation signal.

Expected Result

The output signal will exhibit frequency variations proportional to the input modulating signal, demonstrating FM.
