-The above circuit is gated D latch
Which has just two inputs DATA and ENABLE (CLOCK)
-when HIGH is received at ENABLE point, the DATA is copied to the output.Even if ENABLE input then goes low, the output remains unchanged.
The DATA input is set and reset connected through inverter.
Final output is completely opposite to each other.
The ENABLE pin enables the operation of set and reset pins.

Answers are at the end of the chapter 1. If an S-R latch has a 1 on the S input and a 0 on the R input and then the S input goes to 0, the latch will be (a) set (b) reset (c) invalid (d) clear 2. The invalid state of an S-R latch occurs when (c) S 1,R-1 (d) S-0, R-O 3. For a gated D latch, the output always equals the D input (a) before the enable...
