Digital Electronics is a branch of electronics that deals with circuits and systems that process digital signals—signals that have only two discrete states: 0 and 1 (LOW and HIGH). Instead of working with continuously varying voltages, digital electronics uses binary logic, making it more reliable, noise-resistant, and easier to design than analog systems.
Course Overview
-
Binary System: All operations are performed using 0s and 1s.
-
Logic Gates: The basic building blocks (AND, OR, NOT, NAND, NOR, XOR, XNOR).
-
Combinational Circuits: Circuits where output depends only on current inputs (adders, multiplexers, encoders, decoders).
-
Sequential Circuits: Circuits where output depends on current input and previous states (flip-flops, counters, registers).
-
Number Systems: Binary, decimal, octal, and hexadecimal.
-
Applications: Used in computers, mobile phones, digital watches, calculators, microprocessors, and modern embedded systems.
