## What is a ripple counter explain the working of mod 8 counter?

Table of Contents

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.

## Which type of counter is fastest in operation?

2. Synchronous Counter is faster than asynchronous counter in operation. Asynchronous Counter is slower than synchronous counter in operation.

**How does ripple counter work?**

A ripple counter is an asynchronous counter where only the first flip-flop is clocked by an external clock. All subsequent flip-flops are clocked by the output of the preceding flip-flop. Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops.

### What is the function of the ripple counter?

A counter is basically used to count the number of clock pulses applied to a flip-flop. It can also be used for Frequency divider, time measurement, frequency measurement, distance measurement and also for generating square waveforms.

### How many FFS are needed in a mod-8 ring counter and a mod-8 Johnson counter?

eight flip-flops

For example, a mod-8 ring counter requires eight flip-flops and a mod-16 ring counter would require sixteen flip-flops.

**Which type of counter gives ripple effect?**

asynchronous counter

It is also known as MOD n counter. It is known as ripple counter because of the way the clock pulse ripples its way through the flip-flops. Some of the features of ripple counter are: It is an asynchronous counter.

#### Is ripple counter asynchronous?

The asynchronous counter is also called a ripple counter. For the design of the asynchronous counter, T flip-flops are used. Because the output toggles in T flip-flop.

#### How does a 8 bit ripple counter work?

8-Bit Ripple Counter This circuit is a 8-bit binary ripple counter. All the JK flip-flopsare configured to toggle their state on a downward transition of their clock input, and the output of each flip-flop is fed into the next flip-flop’s clock. So, when each bit changes from 1 to 0, it “carries the one” to the next higher bit.

**How does a MOD-8 counter work?**

A mod-8 counter stores a integer value, and increments that value (say) on each clock tick, and wraps around to 0 if the previous stored value was 7. So, the stored value follows a cycle: 000 001 010 011 100 101 110 111

## How to choose the flip-flop for a ripple counter?

While choosing the type of flip-flop it should be remembered that Ripple counters can be designed only using those flip-flops which have a condition for toggling like in JK and T flip flops. The circuit arrangement of a binary ripple counter is as shown in the figure below. Here two JK flip flops J0K0 and J1K1 are used.

## What is an asynchronous ripple counter?

Ripple Counter: Ripple counter is an Asynchronous counter. It got its name because the clock pulse ripples through the circuit. An n-MOD ripple counter contains n number of flip-flops and the circuit can count up to 2 n values before it resets itself to the initial value.
