The ETB-232 DSB/SSB Amplitude Modulation & Demodulation Trainer is a comprehensive training system designed to demonstrate the principles of Double Sideband (DSB) and Single Sideband (SSB) modulation and demodulation techniques. This trainer enables students to observe and analyze the waveform characteristics, bandwidth, and performance of both modulation types. It includes built-in RF signal generators, carrier and modulating signal sources, and demodulator circuits, allowing easy experimentation. The unit is perfect for communication labs in technical institutes, helping students grasp the practical implementation of analog modulation methods widely used in radio communications.
