Question

1. What are two other names for a D?latch?

2. (T/F) A D?latch cannot be enabled by a clock.

3. (T/F) The D?latch in this diagram is level sensitive on its Enable input.

4. If a clock is applied to the D?latch enable input, what would the frequency be on Q?

5. If you have a positive edge triggered D?latch, when will the input of D be seen on the Q output?

6. (T/F) A D?type flip?flop cannot be used as a single bit memory device.

7. How can a D flip?flop be changed to work like an RS flip?flop?

8. Will this circuit work as a D?latch? Prove your answer by working all possible input

combinations through the circuit.

Explanation / Answer

1)D-latch also called as transparent latch, data latch, or simply gated latch.

2)True

exp)flipflop and latch are circuits used in electronics to store state infomation .main difference between latch and flipflop is latch is clock only.i.e latch has no clock where as flipflop having clock.

3)True

exp) latch is level sensitive and flipflop is edge sesitive.
