Department of Electronics & Communication Engineering

Digital Electronics Laboratory

This is the laboratory were a student learn how to design and develop digital circuits. It facilitates an in-depth analysis of sequential and combinational type of digital electronic circuits. These include circuits with flip flops, counters, shift registers, sequence generators, code converters, etc.

Almost all the experiments are done using the digital trainer kits.
