Characteristics Equation of Flip flops

RS Flip flops:

The truth table for RS Flip-flop is as follow:

Now let’s draw the K-map and get the equation for output Q. As the Qp and Qbar are compliment of each other so we’ll consider only one of those in K-MAP

D FLIP-FLOP:

Truth table is as:

The equation we get is

JK FLIP-FLOP:

The truth table for JK Flip-flop is as follow:

The equation we get is

T FLIP-FLOP:

THE TRUTH TABLE IS AS

And the equation we get is as:
