What is the function of the ripple counter?
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.
Which counter is ripple counter?
Asynchronous counters
Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops.
What is 4 bit ripple carry counter?
A ripple counter is an asynchronous counter in which the preceding flop’s output clocks all the flops except the first. Asynchronous means all the elements of the circuits do not have a common clock. For example, a 4 bit counter will count from 0000 to 1111.
What is the design procedure of a ripple counter?
It is drawn with 3 flip-flops. Since it is an asynchronous counter, the clock pulse is given only to the first flip-flop. For the other flip-flops, the output of the previous flip-flop is given as the clock pulse for the next flip-flop. The expression obtained from the K-map is drawn using combinational circuits.
What are the two types of counter?
Difference between Synchronous and Asynchronous Counter
| S.No. | Synchronous Counter |
|---|---|
| 1. | In the synchronous counter there are continuous clock input signals with flip-flops used to produce the output. |
| 2. | In the synchronous counter, the operation is faster. |
| 3. | Synchronous counter is also known as Parallel counter. |
What are types of counters?
Counters are of two types. Asynchronous or ripple counters. Synchronous counters.
What is definition 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.
Which type of counters give ripple effect?
Asynchronous counters are sometimes called ripple counters because the data appears to “ripple” from the output of one flip-flop to the input of the next. They can be implemented using “divide-by-n” counter circuits. Truncated counters can produce any modulus number count.
How many states a 6 bit ripple counter have?
1 Answer. An n-bit ring counter has n states. A Johnson counter has 2n states. A ripple counter has 2n states.
What is binary ripple counter?
A binary ripple counter is generally using bistable multivibrator circuits so that cache input applied to the counter causes the count to advance or decrease. A basic counter circuit is shown in Figure 1 using two triggered (T-type) flip flop stages. Each clock pulse applied to the T-input causes the stage to toggle.
What are the advantages and disadvantages of ripple counters?
Advantages / Disadvantages of Asynchronous Counters
- It can be easily designed by D-flip flop or T-flip flop.
- It can be used in low speed circuits.
- It is used as Divide by-n counters.
- They are also used as Truncated counters. (to design any mod number counters, i.e. Mod 4, Mod 3).
How many types of the counter are there?
4. How many types of the counter are there? Explanation: Counters are of 3 types, namely, (i)asynchronous/synchronous, (ii)single and multi-mode & (iii)modulus counter.
How many basic types of counter are?
4. How many types of the counter are there? Explanation: Counters are of 3 types, namely, (i)asynchronous/synchronous, (ii)single and multi-mode & (iii)modulus counter. These further can be subdivided into Ring Counter, Johnson Counter, Cascade Counter, Up/Down Counter and such like.
What is the use of counter?
Counters are used not only for counting but also for measuring frequency and time ; increment memory addresses . Counters are specially designed synchronous sequential circuits, in which , the state of the counter is equal to the count held in the circuit by the flip flops.
What are the types of counters?
Types of Counters
- Asynchronous Counters.
- Synchronous Counters.
- Asynchronous Decade Counters.
- Synchronous Decade Counters.
- Asynchronous Up-Down Counters.
- Synchronous Up-Down Counters.
What are the uses of a counter?
What is asynchronous and synchronous counter?
1. 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 8 bit ripple counter?
This circuit is a 8-bit binary ripple counter. All the JK flip-flops are 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.
What is the modulus of 5 bit ripple counter?
Explanation: The minimum number of flip-flops used in a counter is given by: 2(n-1)<=N<=2n. Thus, for modulus-5 counter: 22 <= N <= 23, where N = 5 and n = 3. Explanation: There are 10 states, out of which MSB is high only for (1000, 1001) 2 times.
How many types of ripple counters are there?
There are two types of counters. Synchronous counters and Asynchronous Counters. The asynchronous counter has many types.
Why are counters used?
What is the function of counter?
The counter counts the number of output pulses from encoder that detects the number of rotation and direction of motor. Phase-shifted method and two-pulse input method can be used. Each axis has this function. The counter value can be written or cleared.

What is the difference between synchronous and ripple counters?
While in Synchronous Counter, all flip flops are triggered with same clock simultaneously and Synchronous Counter is faster than asynchronous counter in operation.
