Product Overview
This Amplitude Modulation & Demodulation using Transistor kit provides a practical platform for studying fundamental communication principles. The circuit utilizes a transistor-based oscillator to generate a stable carrier wave, which is then modulated by an input audio signal. The demodulation stage efficiently recovers the original signal, demonstrating the complete AM transmission process. The kit includes clearly labeled components for easy assembly and troubleshooting, with test points for waveform observation using an oscilloscope. The adjustable carrier frequency allows experimentation with different modulation indices, while the compact PCB design ensures reliable performance in educational settings. The circuit operates on standard DC power, making it compatible with most lab power supplies. This hands-on approach helps users understand key concepts like modulation depth, sideband generation, and envelope detection without requiring complex equipment.
FAQs
