Electronics Engineering Interview Question:

How to convert a JK flip flop into SR flip flop and vice versa, a SR flip flop into D or T flip flop and vice versa?

Submitted by: Administrator

An SR flip flop can be converted to D flip flop by shorting S terminal through a Not gate or inverter and applying it to R terminal and the S terminal is kept the same as in SR flip flop.

To convert SR to JK flip flop an extra input to the gate is applied to first gate in both cases. That is in extra to the input and clock at S an input is also given from complement of Q to get J at S terminal and at K terminal an input from Q is given in extra to input and clock.

JK can be converted to T by shorting J and K terminal of JK flip flop.
