Question

1. How does a latch store a binary value?
2. How many latches are required to store 4 bits?

Answer 1

Answer:

setting the latch is equivalent to storing a binary one. The output Q will become high and the inverted output Q will be pulled low. Resetting has the opposite effect. When both inputs are low, the current state is retained. 2 A latch is simply a temporary binary data storage facility to store bits. A four- bit latch uses four D-type  stage to store them. An eight- bit latches has eight stages joined in the same way. In this circuit implementation, we tie the clock inputs together , and this then becomes the ENABLE control signal.
