WebOct 12, 2024 · Follow the below-given steps to design the synchronous counter. Find the number of flip flops using 2n ≥ N, where N is the number of states and n is the number of flip flops. Choose the type of flip flop. Draw the state diagram of the counter. Draw the excitation table of the selected flip flop and determine the excitation table for the counter. WebModulus Counters, or simply MOD counters, are defined based on the number of states that the counter will sequence through before returning back to its original value. For …

WebApr 7, 2024 · Step 1: The number of flip-flops required to design a mod-5 counter can be determined by using the equation: 2n >= N, where n is equal to the number of flip-flops and N is the mod number. In this case, … WebA counter can shorten its modulus by the non-utilization of all the possible states. Here, the non-utilization states are bypassed with suitable feedback. If the number of utilized states are N, then it is Mod-N counter. For example, a Mod-5 counter utilizes 5 states. Using n flip-flops we can get 2 n states.
