Flip-flops in Asynchronous/Ripple counters are supplied with ______ clock signals.

• Different

• Same

• Moderate

• None of the above

Answer explanation

Flip-flops in Asynchronous/Ripple counters are supplied with different clock signals, allowing them to operate independently and asynchronously.

MOD - 3, MOD - 5, MOD -7 counters are all ______ type of counters.

• Even

• Multiple

• Odd

• Single

Answer explanation

MOD - 3, MOD - 5, MOD -7 counters are all Odd type of counters because they result in odd numbers when divided by the respective modulus values.

Asynchronous counters are used in _____ quantity noise emission.

• High

• Low

• Medium

• Null

Answer explanation

Asynchronous counters are used in low quantity noise emission, making the correct answer choice 'Low'.

How many natural states will there be in a 4-bit ripple counter?

• 4

• 8

• 16

• 32

Answer explanation

A 4-bit ripple counter will have 2^4 = 16 natural states, as each bit can be in one of two states (0 or 1), resulting in a total of 16 possible combinations.

How many types of counters exist?

• Three

• Four

• Five

• Two

Answer explanation

There are two types of counters, as mentioned in the question. The correct answer is Two.

Based on the figure, answer the following questions:

a) Identify the TYPE of the counter.

b) Draw the OUTPUT DIAGRAM of the counter.

c) Draw the truth table of the counter.

Draw the logic circuit for MOD 15 asynchronous counter using negative edge triggered (NGT) clock

One of the major drawbacks to the use of asynchronous counters is ___?___

• Low-frequency applications are limited because of internal propagation delays

• High-frequency applications are limited because of the internal propagation delays

• Asynchronous counters do not have major drawbacks and are suitable for use in high and low-frequency counting applications.

• Asynchronous counters do not have propagation delays, which limits their use in high-frequency applications.

The terminal count of a typical modulus-10 counter is ___?___

• 0000

• 1010

• 1001

• 1111

A ripple counter's speed is limited by the propagation delay of ____?_____

• Each flip-flop

• All the flip-flops and gates

• The flip-flops only with gates

• Only circuit gates
