What is difference between asynchronous and synchronous counters?

In synchronous counter, all flip flops are triggered with same clock simultaneously. In asynchronous counter, different flip flops are triggered with different clock, not simultaneously.

What is LSB and MSB in counters?

The first stage of a counter is the least significant bit (LSB). The last stage of a counter is the most significant bit (MSB).

What is meant by asynchronous counter?

Asynchronous Counters can easily be made from Toggle or D-type flip-flops. They are called “Asynchronous Counters” because the clock input of the flip-flops are not all driven by the same clock signal. Each output in the chain depends on a change in state from the previous flip-flops output.

What are the types of asynchronous counters?

Different types of Asynchronous counters

• 4 bit synchronous UP counter.
• 4 bit synchronous DOWN counter.
• 4 bit synchronous UP / DOWN counter.

Why asynchronous counters are also known as serial counters?

Definition of Asynchronous Counter An asynchronous counter is the one also referred as serial counter as here the flip flops that constitute the counter are connected serially and the input clock pulse is provided to the first flip flop in the connection.

What is LSB example?

Digital data is binary, and like ordinary numerical notation, the left end is the highest digit, while the right end is the lowest digit. For example, 99 in the decimal system is expressed as (MSB)01100011(LSB) in the binary system. In this case, the MSB is 0 and the LSB is 1.

What is the use of ripple counter?

Ripple counter is a special type of Asynchronous counter in which the clock pulse ripples through the circuit. The n-MOD ripple counter forms by combining n number of flip-flops. The n-MOD ripple counter can count 2n states, and then the counter resets to its initial value.
