## 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 we will find each flip-flop has a specific delay time. In ripple counters these delay times are additive and the total …

## Asynchronous 3-bit up down counter

Here we come with asynchronous 3-bit up down counter. Some questions we have to clear during the post. What is up counter? What is down counter? How can we combined both? How Asynchronous 3-bit up down counter construct? How it work? What is up counter? Lets start with UP-Counter. As name suggest it start counting …

## 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 using T flip flops because as we know T flip flop is operate only toggle mode of JK Flip flop. So …

## What is a counter?

To finding out the answer of question what is a counter? We should know as name suggests counter is a digital device which count something. Basically counters are one of the simplest types of sequential networks of digital electronics. And a counter is usually constructed from one or more flip flops that change output accordingly …

## What is a Universal Shift Register?

Now to get the answer of this question what is a Universal Shift Register? To get the answer of above question first we have to know some term related to shift register, like unidirectional shift register, bidirectional shift register. And finally we can easily understand what a Universal Shift Register is? A unidirectional shift register …

## Parallel in parallel out shift register

We already discussed on a) serial in serial out shift register b) serial in parallel out shift register c) parallel in serial out shift register. Now in this post we will see fourth type of register, parallel in parallel out shift register, which is designed such that data can be shifted into or out of …

## Parallel in serial out shift register (PISO)

In our previous post we discussed on Serial in parallel out shift register (SIPO) now in this post we will focus on Parallel in serial out shift register (PISO). As name suggests the input data will enter in parallel that means at a time to all flip flop. And output will get serially. We now …

## Serial in Parallel out Register (SIPO)

As we see in my previous post that construction and working principle of serial in serial out register (SISO). Now we see the construction and working principle of serial in parallel out register (SIPO). In serial in parallel out register (SIPO), the input data is entering and shifted in serially, but output taken in parallel. …

## Serial in Serial out Shift Register (SISO)

From the name Serial in Serial out Shift Register (SISO), it is obvious that this type of register accepts data serially, one bit at a time at the single input line, and shifted to next flip flop serially. The output is also obtained on a single output line in a same serial fashion. Now depending upon …

## What is a shift register in digital electronics ?

In our daily life we used register to store information. For same purpose in digital electronics world a shift register is used.Now we discuss on What is a shift register in digital electronics ?  Register is a group of binary storage cells capable of holding binary information. Now depending upon the size of information, a group …
