Quiz 1

Asynchronous counter also called as..........................................

• Ripple

• Up counters

• Down counters

• Modulus

Answer explanation

Asynchronous counter is also called Ripple counter.

Counters defines the combination of ________ data.

• Digital

• Automated

• Cybernated

• Programmed

Answer explanation

Counters defines the combination of Automated data because they are designed to automatically count and track specific information without manual intervention.

Quantity of Flip flop is depend on number of ______?

• Values

• Digits

• States

• Signals

Answer explanation

Quantity of Flip flop is depend on number of States, as each state in a flip flop requires a separate memory element to store its value.

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

• Each flip- flop

• All flip-flops and gates

• The flip-flops only with gates

• Only circuit gates

Answer explanation

A ripple counter's speed is limited by the propagation delay of each flip-flop.

An asynchronous 4-bit binary down counter changes from count 2 to count 3.

How many transitional states are required?

• 1

• 2

• 8

• 15

Answer explanation

The 4-bit binary down counter has 16 transitional states (2^4). When changing from count 2 to count 3, all 15 remaining states need to be traversed, hence 15 transitional states are required.

Counters defines the combination of ___?____ data.

• Digital

• Automated

• Cybernated

• Programmed

How many types of counters exist?

• 3

• 4

• 5

• 2

Flip-flops in Asynchronous/ Ripple counters are supplies with ___?___ clock signal.

• Different

• Same

• Moderate

• None from the answer

A 4-bit counter has a maximum modulus of ____?_____

• 3

• 6

• 8

• 16

An asynchronous 4-bit binary down counter changes from count 2 to count 3. How many transitional states are required?

• 1

• 2

• 8

• 15
