An encoder is a pivotal digital circuit in modern technology, converting a set of binary inputs into a unique binary code representing the position of the input. It performs the essential function of encoding information from a wide array of parallel inputs to a streamlined serial code, making it indispensable in digital systems. With a maximum of 2^n input lines and ‘n’ output lines, this combinational circuit assigns a unique binary code to each active input. The encoder is not just a theoretical construct; it plays a crucial role in various machinery and systems across multiple industries. From robotics to automation, packaging to imaging, encoders provide motion feedback and control, ensuring efficiency and accuracy in operations. Understanding the function and application of encoders is essential for anyone involved in digital systems design or implementation.

An encoder is a digital circuit that converts a set of binary inputs into a unique binary code. The binary code represents the position of the input and is used to identify the specific input that is active. Encoders are commonly used in digital systems to convert a parallel set of inputs into a serial code.
What is Encoder?
An Encoder is a combinational circuit that performs the reverse operation of a Decoder. It has a maximum of 2^n input lines and ‘n’ output lines, hence it encodes the information from 2^n inputs into an n-bit code. It will produce a binary code equivalent to the input, which is active High. Therefore, the encoder encodes 2^n input lines with ‘n’ bits.
The basic principle of an encoder is to assign a unique binary code to each possible input.
encoders are used in machinery for motion feedback and motion control. Encoders are found in machinery in all industries. You'll find encoders used in cut-to-length applications, plotters, robotics, packaging, conveying, automation, sorting, filling, imaging, and many, many more. You may have never noticed them, but they are there. An encoder is a digital circuit that converts a set of binary inputs into a unique binary code.
