How do I design a 4 bit counter using D flip flops?
When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below figure) to design the circuit….Circuit Design of a 4-bit Binary Counter Using D Flip-flops.

How many possible states are there in mod 4 counter?
There are four states for any modulo–4 counter. N=4 The states are simple: 0, 1, 2, and 3.
How many flip flops are required to make a 4-bit counter?
So, in this, we required to make 4 bit counter so the number of flip flops required is 4 [2 n where n is a number of bits]. Step 2: After that, we need to construct a state table with excitation table.
How to design a synchronous up counter?
Step 1: To design a synchronous up counter, first we need to know what number of flip flops are required. we can find out by considering a number of bits mentioned in the question. So, in this, we required to make 4 bit counter so the number of flip flops required is 4 [2 n where n is a number of bits].
How to design a binary counter using a flip flop?
Count Output Solution: The flip flop to be used here to design the binary counter is D-FF. Let’s draw the excitation table for the D-FF Present State (Q) Input (D) Next State (Q+) 0 0 0 0 1 1 1 0 0 1 1 1 The characteristic equation for the D-FF is: Q+ = D We need to design a 4 bit up counter. So, we need 4 D-FFs to achieve the same.
How many D-FFS are needed to design a 4 bit up counter?
The characteristic equation for the D-FF is: Q+ = D We need to design a 4 bit up counter. So, we need 4 D-FFs to achieve the same. Let’s draw the state diagram of the 4-bit up counter
