## ANALOG TO DIGITAL CONVERTERS

An analog to digital converters, or A/D converter, is the reverse system of a D/A converter, which converts an analog signal to its digital form. In my early post we discussed on how a...

To overcome huge range of resistor used in weighted resistor D/A converter, R-2R ladder D/A converter is introduced. In my previous post I discussed about weighted resistor D/A converter. But the vital problem in...

## Weighted resistor digital to analog Converter

Weighted resistor digital to analog Converter is a very basic D/A converter. By using simple resistor network we can easily build that. As we discuss earlier about how digital to analog converters works you...

## How Digital to Analogue Converters (DAC) works?

It is very important question in digital electronics that How Digital to Analogue Converters (DAC) works? In our real world most of signals are analogue continues in nature. But if we want to process it further we need to...

## Quine McCluskey tabulation method

The Quine McCluskey tabulation method is a very useful and convenient tool for simplification of Boolean functions for large numbers of variables. As we know that the Karnaugh map method is a very useful...

## What are hazards in digital circuit ?

It is very important topic that what are hazards in digital circuit ? When you design any digital circuit you have to consider the hazards in digital circuit. If we want to find the answer...

## Frequency Counter

As name suggest a frequency counter is a special kind of digital circuit that can measure and display the frequency of a signal. In my previous post I discussed on 1) what is a counter?...

## What is a synchronous counter?

In my previous post I discussed on asynchronous counter. Now this post you will find what is a synchronous counter? If we think on the timing delay to perform an operation of counter then...

## Asynchronous 3-bit up down counter

In my previous post on ripple counter we already saw the working principle of up-counter. Now in this post we will see how an up down counter work. As we know that in the...

## Ripple counter

Now in this post we can discuss on ripple counter. As we know from my previous post regarding what is a counter? Now we start with simplest ripple counter circuit which can be built...
