The action or operation of a demultiplexer is opposite to that of the multiplexer. As inverse to the MUX , demux is a one-to-many circuit. With the use of a demultiplexer , the binary data can be bypassed to one of its many output data lines. Demultiplexers are mainly used in Boolean function generators and […]

## Multiplexer(MUX) and Multiplexing

Multiplexer Multiplexing is the property of combining one or more signals and transmitting on a single channel .This is achieved by the device multiplexer. A multiplexer is the most frequently used combinational circuits and important building block in many in digital systems. These are mostly used to form a selected path between multiple sources and […]

## Exclusive-NOR Gate

Exclusive NOR gate is another exclusive gate in the logic gates. In our previous tutorials, we have learned about the Exclusive – OR. This tutorial explains about Exclusive – NOR gate. Exclusive-NOR Gate The operation of Exclusive NOR gate is reciprocal to the Exclusive OR gate’s operation. As the basic AND gate implements the Boolean […]

## Digital Comparator and Magnitude Comparator

Data comparison is needed in digital systems while performing arithmetic or logical operations. This comparison determines whether one number is greater than, equal, or less than the other number. A digital comparator is widely used in combinational system and is specially designed to compare the relative magnitudes of binary numbers. These are also available in […]

## Parity Generator and Parity Check

what is parity bit The parity generating technique is one of the most widely used error detection techniques for the data transmission. In digital systems, when binary data is transmitted and processed , data may be subjected to noise so that such noise can alter 0s (of data bits) to 1s and 1s to 0s. […]

## BCD to 7 Segment LED Display Decoder Circuit

Introduction Most often seven-segment displays are used to display the digits in digital watches, calculators, clocks, measuring instruments and digital counters, etc. Generally, LCD and LED segments provide the display output of numerical numbers and characters. However to display the characters and numbers (in order to produce the decimal readout), seven-segment displays are most commonly […]

## Types of Binary Decoders,Applications

Basically, Decoder is a combinational logic circuit that converts coded input to coded outputs provided both of these are different from one another. The name decoder means translating of coded information from one format into another. So the input code generally has fewer bits than output code word. A digital decoder converts a set of […]

## Priority Encoder Types With Real Time Applications

In the previous tutorial we have seen binary encoders which encode the given data. But a standard digital encoder has one limitation that it would produce an error at its output if more than one input is active at a given time. It generates an undefined combination of outputs, if the two inputs are logic 1 […]

## Binary Encoders And Their Applications

An encoder is a device which converts familiar numbers or characters or symbols into a coded format. It accepts the alphabetic characters and decimal numbers as inputs and produces the outputs as a coded representation of the inputs. It encodes the given information into a more compact form. In other words, it is a combinational […]

## Binary Multiplication Methods

A binary multiplier is a combinational logic circuit used in digital systems to perform the multiplication of two binary numbers. These are most commonly used in various applications especially in the field of digital signal processing to perform the various algorithms. Commercial applications like computers, mobiles, high speed calculators and some general purpose processors require […]
