POP QUIZ COUNTER

The example of sequential circuit is

• Multiplexers

• Decoders

• 7 Segment display

• Counters

A 4 bit counter requires

• 3 FF

• 4 FF

• 5 FF

• 6FF

The maximum number of states in 4 bit synchronous counters

• 4

• 8

• 10

• 16

Synchronous counters eliminate the delay problems encountered with asynchronous counters because the:

• input clock pulses are applied only to the first and last stages

• input clock pulses are applied only to the last stage

• input clock pulses are not used to activate any of the counter stages

• input clock pulses are applied simultaneously to each stage
