The Pulse Modulations Trainer, “EMDA/P”, is a complete modulations trainer designed to explain the basic concepts of pulse modulation. It covers the principles of many of the modulation and demodulation techniques used in modern communication systems. The trainer provides a basic understanding of the concepts behind pulse communications techniques: Pulse Code Modulation (PCM), Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), Pulse Density Modulation (PDM), Pulse Position Modulation (PPM). Finally, it allows students to study the basic principles of Time Division Multiplexing (TDM) and Frequency Division Multiplexing (FDM) are introduced.

All elements are mounted in a metallic box, with power supply and block diagram.
