Why it is called master-slave flip-flop?

The first flip flop is called the master flip-flop and the next is called the slave flip-flop. Master is triggered by external clock pulse while the slave is activated at its inversion. If the master is positive edge-triggered, then the slave is negative edge triggered, and vice-versa.

What is master-slave flip-flop explain with diagram?

Master-slave flip flop is designed using two separate flip flops. Out of these, one acts as the master and the other as a slave. The output of the master J-K flip flop is fed to the input of the slave J-K flip flop. The output of the slave J-K flip flop is given as a feedback to the input of the master J-K flip flop.

What is master-slave flip-flop truth table?

Master Slave flip flop are the cascaded combination of two flip-flops among which the first is designated as master flip-flop while the next is called slave flip-flop (Figure 1).

What is the difference between a latch and a flip-flop?

Both latches and flip-flops are circuit elements whose output depends not only on the current inputs, but also on previous inputs and outputs. The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop always does.

What is the difference between JK and master-slave flip flop?

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 JK flip flop?

Master slave flip flops of any variety are usually a combination of a positive level controlled flop with a negative level controlled flop. When combined properly this gives you an edge controlled flop. It is easier to design sequential logic which is controlled by one edge rather than two levels.

How many flip flops are needed for a mod 32 binary counter?

For a mod 32 counter, 32=2^5. So 5 flip-flops are required.

Which flip-flop is used as latch?

RS flip-flop is used as a latch.

What is the advantage of flip flop over latch?

Flip-flops (FFs) are edge triggered on the clock, so their latch phase is shorter, therefore more time is left to perform combinatorial logic calculations compared to transparent latches having the same clock.

Where is Flip Flop used?

It is the basic storage element in sequential logic. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems. Flip-flops and latches are used as data storage elements.

Which flip flop is used as latch?
