What is flip flop / types of flip flop /Sr flip flop/

we discus as that are the properties and working of flip flop.

           Flip-Flops

Introduction

The term flip-flop (FF) was invented in the year 1918 by the British physicist F.W Jordan and William Eccles. It was named as the Eccles Jordan trigger circuit and includes two active elements. The design of the FF was used in the British Colossus code-breaking computer the year 1943. The transistorized versions of these circuits were common in computers, even after the overview of integrated circuits, though FFs made from logic gates are also common now. The first flip-flop circuit was known differently as multivibrators or trigger circuits.

FF is a circuit element where the o/p not only depends on the present inputs but also depends on the former input and o/ps. The major difference between flip flop circuit and a latch is that a FF includes a clock signal, whereas a latch doesn’t. Basically, there are four kinds of latches & FFs namely: T, D, SR, and JK. The major differences between these kinds of FFs and latches are the number of inputs they have and how they alter the states. There are different differences for each kind of FFs and latches which can increase their operations. Please follow the below link to know more about Different types of flip flop conversion

             What is a Flip Flop Circuit?

The designing of the flip flop circuit can be done by using logic gates such as two NAND and NOR gates. Each flip flop consists of two inputs and two outputs, namely set and reset, Q and Q’. This kind of flip flop is stated to as an SR flip flop or SR latch.

The FF includes two states shown in the following figure. When Q=1 andQ’=0 then it is in the set state. When Q=0 and Q’=1then it is in the clear state. The FF’s outputs Q and Q’ are complements of each other and that are stated to as the normal & complement outputs respectively. The binary state of the flip flop is taken to be the normal output value.

When the input 1 is applied to the flip flop, both the outputs of the FF go to 0, so both the o/p’ s are complements of each other. In regular operation, this ailment must be neglected by making sure that ones are not appli

                        Applications of Flip Flops

Application of the flip flop circuit mainly involves in bounce elimination switch, data storage, data transfer, latch, registers, counters, frequency division, memory, etc. 

                    Types of Flip Flops

Flip flop circuits are classified into four types based on its use, namely.   

Ø  

D-Flip Flop,

Ø  

T- Flip Flop,

Ø SR- Flip Flop

Ø JK- Flip Flop.

                SR Flip-Flop

The SR flip-flop, also known as a SR Latch, can be considered as one of the most basic sequential logic circuit possible. This simple flip-flop is basically a one-bit memory bistable device that has two inputs, one which will “SET” the device (meaning the output = “1”), and is labelled S and one which will “RESET” the device (meaning the output = “0”), labelled R.

Then the SR description stands for “Set-Reset”. The reset input resets the flip-flop back to its original state with an output Q that will be either at a logic level “1” or logic “0” depending upon this set/reset condition.
