What is 3-bit ripple counter?
The number of states that a counter owns is known as its mod (modulo) number. Hence a 3-bit counter is a mod-8 counter. A mod-n counter may also be described as a divide-by-n counter.
How many natural states will there be in a 3-bit ripple counter?
Therefore, in a 3-bit counter, the total number of states = 23 = 8 states.
What is 4-bit ripple counter?
This circuit is a 4-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 2 bit ripple counter?
Binary Ripple Counter
A Binary counter is a 2-Mod counter which counts up to 2-bit state values, i.e., 22 = 4 values. The flip flops having similar conditions for toggling like T and JK are used to construct the Ripple counter. Below is a circuit diagram of a binary ripple counter.
Why is it called ripple counter?
Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops.
What is the use of ripple counter?
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.
How many different states does a 3-bit?
How many different states does a 3-bit asynchronous down counter have? Explanation: In a n-bit counter, the total number of states = 2n. Therefore, in a 3-bit counter, the total number of states = 23 = 8 states.
How many clock pulses are required for a 3-bit ripple counter?
3-bit binary up/down ripple counter. 3-bit − hence three FFs are required. UP/DOWN − So a mode control input is essential. For a ripple up counter, the Q output of preceding FF is connected to the clock input of the next one.
How many states a 6 bit ripple counter can have ____?
Ripple Counter MCQ Question 6
For a counter with ‘n’ flip flops: The total number of states = 2n (0 to 2n – 1) The largest number that can be stored in the counter = 2n – 1.
How many states are there in 3 bit ring counter?
The number of states used is 4 (Where no of states = no of flip flops used).
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.
What are the types of counters?

Why it is called ripple counter?
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.
Which counter is ripple counter?
Asynchronous counters
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.
How BCD counter is also called?
BCD or Decade Counter Circuit. A binary coded decimal (BCD) is a serial digital counter that counts ten digits . And it resets for every new clock input. As it can go through 10 unique combinations of output, it is also called as “Decade counter”.
How many different states does a 3 bit asynchronous counter have?
8 states
How many different states does a 3-bit asynchronous down counter have? Explanation: In a n-bit counter, the total number of states = 2n. Therefore, in a 3-bit counter, the total number of states = 23 = 8 states.
How many clock pulses are required for a 3 bit ripple counter?
What is D flip flop in digital electronics?
The D flip-flop is a clocked flip-flop with a single digital input ‘D’. Each time a D flip-flop is clocked, its output follows the state of ‘D’. The D Flip Flop has only two inputs D and CP. The D inputs go precisely to the S input and its complement is used to the R input.

What is 4 bit counter?
4-bit Synchronous Counter Waveform Timing Diagram
Because this 4-bit synchronous counter counts sequentially on every clock pulse the resulting outputs count upwards from 0 ( 0000 ) to 15 ( 1111 ). Therefore, this type of counter is also known as a 4-bit Synchronous Up Counter.
What is counter used for?
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 is ripple counter explain?
What is ripple factor?
What is Ripple Factor? The ripple factor is defined as. The ratio of the RMS value of an alternating current component in the rectified output to the average value of rectified output. The ripple factor is denoted as γ. It is a dimensionless quantity and always has a value less than unity.
