Digital Modulations Trainer - EMDA/D

State: Out of stock

EMDA/D is a complete digital communications trainer designed to explain the basic concepts of digital modulation.
It covers the principles of many of the modulation and demodulation techniques used in modern digital communication systems.
The trainer provides a basic understanding of the concepts behind digital communications techniques: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), Phase Shift Keying (PSK) and Quadrature Phase Shift Keying (QPSK). It allows students to study some of the line coding techniques like NRZ(L), NRZ(M), RZ, RB, etc.
All elements are mounted in a metallic box, with power supply and block diagram.
