The ETB-234 DSB / SSB AM Receiver Trainer is an educational training system designed to demonstrate the reception and demodulation of Double Sideband (DSB) and Single Sideband (SSB) amplitude-modulated signals. This trainer simulates a practical AM receiver, incorporating RF amplifier stages, mixers, local oscillators, IF amplifiers, product detectors, and audio recovery circuits. It allows students to study the process of tuning, filtering, and demodulating AM signals in both DSB and SSB formats. Ideal for engineering colleges, technical institutes, and vocational training programs, the ETB-234 offers a clear view into analog communication receiver principles.
