Description
The Adaptive Delta Modulation & Demodulation Trainer is a comprehensive communication laboratory apparatus designed to demonstrate the working principles of Adaptive Delta Modulation (ADM), an improved form of delta modulation used to reduce slope overload and granular noise. This trainer enables students to study step-size adaptation, signal tracking accuracy, and reconstruction of analog signals from digitally modulated data.
Ideal for communication engineering labs, electronics laboratories, universities, polytechnic institutes, and technical training centers.
