What is "Tcd"? It can't be time from clock to data, since that doesn't apply to anything other than the flip flop.

Where is YOUR attempt to solve YOUR homework problem?

Tcd is the lil time which remains constant as the input before the clock..

My attempt is how to find the min T for being the system worked properly?

So what does a "lil time which remains constant as the input before the clock" of "4" mean for a AND or an OR gate or of "1" for a NOT gate?

Answer: Since none of these gates have a clock, it is meaningless.

SHOW your attempt to answer the problem!

This is YOUR homework.
