Question

What is the relationship between clock period ($ t_c $) and propagation delay ($ t_p $) when a racing condition occurs in a JK flip-flop?

• A. \( t_p<t_c \)
• B. \( t_c<t_p \)
• C. \( t_p = t_c \)
• D. No relation between \( t_p \) and \( t_c \)

Hint:

For JK flip-flops, make sure the clock period is smaller than the propagation delay to prevent racing conditions.

Answer 1

The Correct Option is B

In JK flip-flops, when racing conditions occur, the clock period must be greater than the propagation delay in order to avoid unstable states. This ensures the stable transfer of the input to the output.
Thus, the correct relationship is \( t_c<t_p \).
Thus, the correct answer is \( t_c<t_p \).
