SR Flip-Flop:

In this video, first, the importance of Flip-Flop over the latch in the Sequential Circuits is explained using one example.
And then the working of the positive and the negative edge-triggered SR flip-flops are explained using the truth table and the timing diagram.

The characteristic Equation of the SR Flip-Flop:

The characteristic equation of the Flip-Flop shows the output of the flip-flop in terms of the present state and the inputs.
For SR Flip-Flop if Qn is the present state and, S and R are the inputs, then the next state of the Flip-Flop (Q n+1) can be given as
Q n+1 = S + R' Qn

In this video, the characteristic equation of the SR flip-flop is derived, and in the later part of the video, the pulse transition detection circuit for the Flip-Flop is also discussed.

This video will be useful to all the students of science and engineering in understanding the working of the SR Flip-Flop.
