Basics of Digital Electronics and Applications in Electronic Devices

Electrical Engineering

Published on Jun 02, 2024

Digital electronics is a branch of electronics that deals with digital signals and the systems that use such signals. Unlike analog electronics, which involves continuous signals, digital electronics works with discrete, binary signals. These signals are represented by 0s and 1s, and are processed using logic gates to perform various operations.

The fundamental building blocks of digital electronics include logic gates, flip-flops, counters, registers, and multiplexers. These components are combined to create complex digital systems that form the basis of electronic devices we use in our daily lives.
