Question

Construct a SR latchfrom

1) two NAND gates.

2) two NOR gates

3)Also construct SR Latch with a control input.

Answer 1

Refer to the images for different S-R Latches.

There are 3 images attached 1 having S-R latch with 2 NAND gates 2nd having S-R Latch with 2 NOR gates and last having S-R latch with control input.

Difference between NAND gated S-R latch and NOR gated S-R latch is the output is reversed.

In latch with control input the latch will only work when the control input or Enable signal in our image is HIGH or 1.
