Ratio Detector Trainer is a specialized educational kit designed to demonstrate the working principle of a ratio detector circuit, commonly used for FM (Frequency Modulation) demodulation. It helps students understand FM detection, frequency-to-voltage conversion, and the behavior of detector circuits in communication systems.
Typical Experiments
• Study of FM demodulation using ratio detector.
• Comparison with other FM demodulation techniques (e.g., Foster-Seeley discriminator).
• Observation of input FM waveform and output demodulated signal on CRO.
• Analysis of detector linearity and distortion.
• Study of the effect of signal-to-noise ratio on demodulation.
