Counter Design Quiz

What is a synchronous Counter?

• A counter where all flip-flops are clocked simultaneously

• A counter where only the last flip-flop is clocked externally

• A counter that counts in reverse order only

• A counter that does not require any flip-flops

In an asynchronous counter, each flip-flop is triggered by:

• The external clock signal

• The output of the preceding flip-flop

• A specific enable signal

• The sum of all flip-flops' outputs

What is the main disadvantage of asynchronous (ripple) counters?

• They are expensive

• They consume too much power

• Propagation delay accumulates through each flip-flop stage

• They cannot count in both directions

A BCD ripple counter counts from:

• 0 to 9

• 0 to 15

• 0 to 255

• 0 to 999

In a synchronous counter, all flip-flops are triggered by:

• The output of a preceding flip-flop

• An asynchronous signal

• A common clock signal

• The external reset signal

What is the purpose of state reduction in counter design?

• To increase the number of states in a counter

• To reduce the number of flip-flops required

• To enhance clock frequency

• To increase propagation delay

Which of the following counters can count in both upward and downward directions?

• Asynchronous counter

• Synchronous counter

• Up/Down counter

• Ring counter

In a Modulo-n counter, 'n' represents:

• The number of flip-flops

• The number of states the counter cycles through

• The propagation delay per state

• The modulus of the counter's frequency

How many flip-flops are needed to design a Mod-16 synchronous counter?

• 2

• 3

• 4

• 5

Which counter is also known as a Twisted Ring Counter?

• Ripple counter

• Johnson counter

• BCD counter

• Modulo-n counter
