TRUE of FALSE ( I hope I can get explanation as well )

1) A shift register cannot use level-sensitive latches.

2) The state of the S-R latch when S = R = 1 is predictable.

3) A digital switch that connects the input to a selected output is called a multiplexer.

4) In a flip-flop circuit, output can change only once during a clock cycle.

5) When using single cell meomery element called a \"latch\", the state of the latch can change during the \"active\" level of the \"Clock\".

Solution

ANSWER:

1. FALSE. It is not a sin to use latches instead of flops for a shift register. But, since we generally have ciruits, which are clocked at a frequency, it becomes tough to handle a latch since the latch shift register will always get updated whenever the clk is active. But for a flop shift register, it gets updated only when there is an edge (transition- positive or negative) in the clk.

2. FALSE. This depends if the SR latch is made on NAND gates or NOR gates.

3. FALSE. It is called a de-multiplexer.  A digital switch that connects the output to a selected input is called a multiplexer.

4. FALSE. Generally, flops are either positive or negative edge triggered. But, we do have flops which are dual edge triggered, i.e. they get updated at both the clock transitions.

5. TRUE
