ETB-118 – Study of Crystal Detector Trainer is an instructional model designed to explore the working principle and characteristics of a crystal detector—a fundamental component in early radio receivers. This trainer enables students to understand how semiconductor diodes (such as germanium diodes) function as demodulators by detecting amplitude-modulated signals.
The setup includes a built-in regulated power supply, two measuring meters for current and voltage monitoring, and all necessary circuit components to study the detection process. It is particularly useful in understanding AM signal detection, diode behavior, and signal rectification in RF circuits.
Key Features:
Demonstrates the principle of crystal diode-based AM detection
Built-in power supply and two analog/digital meters for real-time measurements
Clear circuit layout with accessible test points for CRO connection
Facilitates observation of detected waveform
Enhances understanding of early radio receiver technology
Ideal for communication systems, electronics, and RF circuit labs
Includes components suitable for continuous practical use
