# What is master-slave FF?

## What is master-slave FF?

master-slave flip-flop A type of clocked flip-flop consisting of master and slave elements that are clocked on complementary transitions of the clock signal. Data is only transferred from the master to the slave, and hence to the output, after the master-device outputs have stabilized.

## What are RS flip-flops?

The R-S flip-flop is used to temporarily hold or store information until it is needed. A single R-S flip-flop will store one binary digit, either a 1 or a 0. Storing a four-digit binary number would require four R-S flip-flops. The standard symbol for the R-S flip-flop is shown in the figure below.

What is master-slave latch?

A master-slave latch, commonly known as flip-flop, is an edge triggered device, meaning that it will only perform its full function when the signal changes instead of using a signal level.

### What is limitation of RS FF?

The limitation with a S-R flip-flop using NOR and NAND gate is the invalid state. This problem can be overcome by using a stable SR flip-flop that can change outputs when certain invalid states are met, regardless of the condition of either the Set or the Reset inputs.

### What is the difference between JK and master-slave JK F F?

In master slave JK flip flop , the output of master change many times but slave output change only one time so master flip flop act as level triggered and slave flip flop act as edge triggered by which race around condition does not take place at the output of slave flip flop .

What are the advantages of master-slave flip-flop?

The output in master slave changes when negative edge of clock reaches i.e negative triggers at negative edge which also removes problem due to propagation delay. This toggling effect helps in designing counters. Master slave configuration make the circuit edge sensitive which helps to control race around condition.

#### Why NAND gate is used in flip-flop?

A basic NAND gate SR flip-flop circuit provides feedback from both of its outputs back to its opposing inputs and is commonly used in memory circuits to store a single data bit.

#### What is the advantage of a master-slave flip-flop?

The master-slave configuration has the advantage of being edge-triggered, making it easier to use in larger circuits, since the inputs to a flip-flop often depend on the state of its output.

What are the advantages of master-slave J-K flip-flop?

Advantages of Master Slave JK Flip Flop JK flip flop master slave over come the limitation of SR flip flop, in SR flip flop when S = R = 1 condition arrives the output become uncertain, but in JK master slave when J = K = 1, then the output toggles, the output of this state keep changing with the clock pulse.

## What is a trigger pulse Sanfoundry?

Explanation: Trigger pulse is defined as a pulse that starts a cycle of operation.

## What is the problem with JK flip flop?

JK flip-flop has a drawback of timing problem known as “RACE”. The condition of RACE arises if the output Q changes its state before the timing pulse of the clock input has time to go in OFF state. The timing pulse period (T) should be kept as short as possible to avoid the problem of timing.
