A NAND based S’-R’ latch can be converted into S-R latch by placin

1.	A NAND based S’-R’ latch can be converted into S-R latch by placing ____________(a) A D latch at each of its input(b) An inverter at each of its input(c) It can never be converted(d) Both a D latch and an inverter at its inputThe question was asked during an online interview.I want to ask this question from Flip Flops topic in division Flip-Flops of Digital Circuits
Answer» The correct choice is (d) Both a D LATCH and an inverter at its input Explanation: A NAND based S’-R’ latch can be converted into S-R latch by PLACING either a D latch or an inverter at its input as it’s operations will be COMPLEMENTARY.
