# How 4 bits up counter works explain?

## How 4 bits up counter works explain?

In the asynchronous 4- bit up counter, the flip flops are connected in toggle mode, so when the when the clock input is connected to first flip flop FF0, then its output after one clock pulse will become 20. The rising edge of the Q output of each flip flop triggers the clock input of its next flip flop.

What is 4-bit counter?

For example, a four-bit counter can have a modulus of up to 16 (2^4). Counters are generally classified as either synchronous or asynchronous. In synchronous counters, all flip-flops share a common clock and change state at the same time.

What is a 4-bit ripple counter?

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.

### How many flip-flops are needed for a 4-bit counter?

4 flip-flops
Detailed Solution. A four-bit counter is designed using 4 flip-flops and a corresponding combinational circuit. It can count from 0 to 2n – 1 i.e. 2n numbers.

What is 4-bit ripple counter?

Which one is a 4-bit binary ripple counter?

Which one is a 4-bit binary ripple counter? Explanation: IC 7493 is a 4-bit binary ripple counter. It is a MOD-16 counter with 24 = 16 states. Explanation: IC 7493 consist of 4 J-K master-slave flip-flop.

## What is 4-bit up down counter how many flip-flops are required?

In a 4-bit up-down counter, there are 4 J-K flip-flops required. For modulus-10 counter, N = 10.

How many natural 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.

Is the clock is synchronized in a ripple counter of 4-bit?

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.
