1. Build and test D-type Flip-Flop using a built-in SR flip-flop.
GaryK [48]

Answer:

The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops

Explanation:

An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'

A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.

D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.

Ivan

Answer:

C. Am I carrying money?

Explanation:

The options are:

A. Am I awake and alert?

C. Am I carrying money?

The correct option is certainly C. Am I carrying money? It can also be a concern if you are worrying since we don't have money. However, here its mentioned, we are not carrying, and it's not like we don't have money, and hence, it is not going to affect our mindset. Hence, it is not an assessment of anybody's fitness to drive.
