Electronics And Communication Test Preparations On Sequential Logic Circuits Part 1

Test Preparation on Electronics And Communication Test Preparations On Sequential Logic Circuits Part 1

1.

A ripple counter's speed is limited by the propagation delay of:

1each flip-flop
2all flip-flops and gates
3the flip-flops only with gates
4only circuit gates

2.

To operate correctly, starting a ring counter requires:

1clearing all the flip-flops
2presetting one flip-flop and clearing all the others
3clearing one flip-flop and presetting all the others
4presetting all the flip-flops

3.

What type of register would shift a complete binary number in one bit at a time and shift all the stored bits out one bit at a time?

1PIPO
2SISO
3SIPO
4PISO

4.

Synchronous counters eliminate the delay problems encountered with asynchronous (ripple) counters because the:

1input clock pulses are applied only to the first and last stages
2input clock pulses are applied only to the last stage
3input clock pulses are not used to activate any of the counter stages
4input clock pulses are applied simultaneously to each stage
