one D memory units. The memory units are either latches or flip$-$flops, depending on the question. They are

working in positive logic.

Question $6$: $[10$ marks: $5$ marks each$]($Moderate but Tricky$)$

Given the circuit in Figure $1$ in positive logic, complete the timing diagram if the memory units are:

a$.$ Latches.

b$.$ Flip$-$flops.
