Frequency Modulation and Demodulation Trainer is a purpose-built educational system designed to provide hands-on training in the principles and practical implementation of FM (Frequency Modulation) and FM Demodulation techniques.
Key Features:
• FM Modulator Circuit: Demonstrates frequency modulation of a high-frequency carrier signal using a low-frequency analog input (e.g., audio signal).
• FM Demodulator Circuit: Includes phase-locked loop (PLL) or slope detection methods for extracting the original message from the FM waveform.
Educational Objectives:
• Understand the concept of frequency modulation and its advantages over amplitude modulation.
• Learn different demodulation techniques to retrieve the original message signal.
• Analyze FM waveforms in time and frequency domains.
• Explore practical issues like bandwidth
