ETB-113 – Pulse Width Modulation & Demodulation (PWM) Trainer is a comprehensive educational system designed to demonstrate the concepts and practical implementation of PWM signal generation and its demodulation. PWM is a key technique used in power control, signal processing, and communication systems, where the width of each pulse in a pulse train corresponds to the amplitude of the analog input signal.
This trainer features a built-in regulated power supply, signal generation blocks, and clearly marked test points to allow students to observe and analyze the modulated waveforms and understand the demodulation process using filters and reconstruction circuits.
Key Features:
Demonstrates both Pulse Width Modulation and Demodulation
Built-in power supply for easy standalone operation
Well-labeled test points for waveform analysis via CRO
Enables understanding of time-domain and pulse-based modulation
Illustrates signal reconstruction techniques through filtering
Ideal for analog/digital communication and signal processing courses
Useful in studying applications like motor control and power electronics
