ETB-097 – Amplitude Modulation and Demodulation Trainer with Power Supply and Oscillator is an advanced version of the AM trainer system, incorporating both carrier and modulating signal oscillators for complete in-house signal generation. This allows students to study amplitude modulation without requiring external signal sources. It demonstrates modulation of a high-frequency carrier by a lower-frequency audio signal and subsequent demodulation using envelope detection or diode detectors.
This unit includes a regulated power supply, inbuilt audio and carrier oscillators, and accessible test points for waveform observation via a CRO. It is ideal for hands-on learning in analog communication systems.
Key Features:
Complete AM modulation and demodulation setup with built-in oscillators
Integrated carrier and modulating signal sources
Demonstrates envelope detection and recovery of the original signal
Built-in regulated DC power supply
Test points provided for waveform observation and frequency analysis
Clear and educational circuit layout with component labeling
Suitable for analog communication, signal processing, and electronics courses
