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 […]

## Phasors and Phasor Algebra

The ‘Phasor’ is defined as “The complex number in the polar form with which we can analyze the circuit”. It is a vector quantity. In this vector representation we use Cartesian plane. The Y axis represents the magnitude and phase angle of the waveform in the form of imaginary quantities and X axis represents real […]

## Phase Difference and Phase Shift

The position of a wave particle of a periodic waveform is known as “Phase” of a waveform. The complete phase of a full cycle of a waveform is 3600. When two or more waves of the same frequency are interfering in a medium or made to travel in the same path, then the “phase” 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 […]

## Binary Adder and Subtractor

The operation of adding two binary numbers is one of the fundamental tasks performed by a digital computer. The four basic addition operations are 0 + 0 = 0, 1 + 0 = 1, 0 + 1 = 1 and 1 + 1 = 10. In the first three operations, each binary addition gives sum […]

## Carry-Lookahead Adder

In case of parallel adders, the binary addition of two numbers is initiated when all the bits of the augend and the addend must be available at the same time to perform the computation. In a parallel adder circuit, the carry output of each full adder stage is connected to the carry input of the […]

## Introduction to Counters

Like shift registers and other combinational circuits, there is another important element in digital electronics which we use most. They are counters. Counters are used not only for counting but also for measuring frequency and time ; increment memory addresses . Counters are specially designed synchronous sequential circuits, in which , the state of the […]
