Which of the following enables us to eliminate the undefined state in an SR latch?Group of answer choicesD LatchJK flip - FlopNoneT flip - flop

The D Latch enables us to eliminate the undefined state in an SR latch.

Here's why:

1. An SR latch has two inputs: Set (S) and Reset (R). When both inputs are 1, the latch enters an undefined or invalid state. This is a problem because it can lead to unpredictable behavior.

2. A D latch (or Data latch) solves this problem. It also has two inputs, but they are Data (D) and Enable (E). The D input is connected to the S input of the SR latch, and the inverse of the D input (not D) is connected to the R input.

3. This means that the S and R inputs of the SR latch can never be 1 at the same time, because they are always opposites of each other. Therefore, the undefined state is eliminated.

4. The JK flip-flop and T flip-flop are more complex devices that also eliminate the undefined state, but they do so in different ways and are not the simplest solution. The D latch is the simplest device that eliminates the undefined state in an SR latch.
