My problem is to implement a solution that changes D latch to D Flip-Flop, using simple logic, and present the circuit that comes with this solution. Can you help me?

PS: If it's not the right place, move it, i'm new in the forum.

A latch is simply an enable signal and a D input. A flip-flop adds SET and RESET inputs, and so becomes more complex.

Have you got the logic for the latch function yet?

on the clock input of the D latch place an AND gate with two inputs (say A nad B). Connect A to three NOT gates in series and then connect the input of the last NOT gate in the tail to B. use B as your clock input. This is for a positive edge. For a negative edge replace the AND gate with a NOR.

Technically, SET and RESET inputs are not required for a flip-flop. They are just typically there.
