Question

i have to design a 4-bit even up-counter using D flip flop by converting combinational circuit to sequential circuit. The counter will only consider even inputs and the sequence of inputs will be 0-2-4-6-8-10-0. i need help...

Answer 1

ok so the D flip flop is in an implitical order which i assume you know, using this fact you want to use it in the sequence to find the inputs
