## How many states are there in 3-bit counter?

Since there are eight states, the number of flip-flops required would be three. Now we want to implement the counter design using JK flip-flops.

## How many of states are there in a 2 bit counter?

2 bit asynchronous Up counter. It can generate 4 different unique states. This is known as divide by 4 circuits or mod 4 ripple counter. Here output is taken as Q1(MSB) Q0(LSB). If there are n FFs then the output frequency will be divide by 2n.

**How many different states does it 2 bit asynchronous counter have?**

An Asynchronous counter can have 2n-1 possible counting states e.g. MOD-16 for a 4-bit counter, (0-15) making it ideal for use in Frequency Division applications.

**How many different states does A to B?**

A map of the United States showing its 50 states, federal district and five inhabited territories. Note that Alaska, Hawaii, and territories are shown at different scales and that the Aleutian Islands and the uninhabited northwestern Hawaiian Islands are omitted from this map.

### What is a 3 bit up counter?

The 3-bit Synchronous binary up counter contains three T flip-flops & one 2-input AND gate. The output of first T flip-flop toggles for every negative edge of clock signal. The output of second T flip-flop toggles for every negative edge of clock signal if Q0 is 1.

### How many flip flops are needed for a 3 bit counter?

In a sense, this circuit “cheats” by using only two J-K flip-flops to make a three-bit binary counter. Ordinarily, three flip-flops would be used—one for each binary bit—but in this case, we can use the clock pulse (555 timer output) as a bit of its own.

**How many natural states will there be in a 4-bit ripple counter a 4 B 8 C 16 D 32?**

How many natural states will there be in a 4-bit ripple counter? Explanation: In an n-bit counter, the total number of states = 2n. Therefore, in a 4-bit counter, the total number of states = 24 = 16 states.

**What is 3-bit asynchronous down counter?**

The 3-bit Asynchronous binary up counter contains three T flip-flops and the T-input of all the flip-flops are connected to ‘1’. All these flip-flops are negative edge triggered but the outputs change asynchronously. The clock signal is directly applied to the first T flip-flop.

#### What is a 3-bit asynchronous counter?

#### What is a 3-bit counter?

The 3-bit Asynchronous binary up counter contains three T flip-flops and the T-input of all the flip-flops are connected to ‘1’. All these flip-flops are negative edge triggered but the outputs change asynchronously. The output of first T flip-flop is applied as clock signal for second T flip-flop.

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

16 states

1. How many natural states will there be in a 4-bit ripple counter? Explanation: In an n-bit counter, the total number of states = 2n. Therefore, in a 4-bit counter, the total number of states = 24 = 16 states.

**How many different states does a 3 bit asynchronous counter have?**

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

1. How many natural states will there be in a 4-bit ripple counter? Clarification: In an n-bit counter, the total number of states = 2n. Therefore, in a 4-bit counter, the total number of states = 24 = 16 states. 2. A ripple counter’s speed is limited by the propagation delay of _____________

## What is the total number of States in a binary counter?

Clarification: 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. 9. A 5-bit asynchronous binary counter is made up of five flip-flops, each with a 12 ns propagation delay.

**What is the total number of transitional states in a ripple counter?**

Clarification: Transitional state is given by (2n – 1). Since, it’s a 4-bit counter, therefore, transition states = 24 – 1 = 15. So, total transitional states are 15. 11. A 4-bit ripple counter consists of flip-flops, which each have a propagation delay from clock to Q output of 15 ns.

**How many transitional states are required for an asynchronous binary down counter?**

An asynchronous 4-bit binary down counter changes from count 2 to count 3. How many transitional states are required? Clarification: Transitional state is given by (2n – 1). Since, it’s a 4-bit counter, therefore, transition states = 24 – 1 = 15. So, total transitional states are 15.
