The Master-Slave JK Flip-Flop:

The Master-Slave JK flip-flop consists of two gated SR latches. One latch acts as a master latch, while the other acts as a slave latch. The J and K inputs are applied to the master latch. Apart from that, the outputs of the Slave latches are connected back to the master latch to use the SR latch as the JK latch.
In this Master-Slave Flip-Flop, the clock signal is directly applied to the master latch and it is connected to the slave latch via an inverter (NOT gate). Therefore, at a time only one latch is active.
In the master-slave configuration, during the ON time of the clock, the master responds to the input. And during the OFF time of the clock, the slave latch follows the master output.
Since at a time, only one latch is active, this configuration avoids the race around condition, which is typically seen in the JK Flip-Flop.

In this video, the working of the master-slave JK flip-flop is explained using the timing diagram.

This video will be helpful to all the students of science and engineering in understanding the Master-Slave Flip-Flop.
