Question

Which of the following conditions must be met to avoid race around problem?

• A. $\Delta t< t_{p}< T$
• B. $T>\Delta t> t_{p}$
• C. $2t_{p}< \Delta t< T$
• D. none of these

Answer 1

OPTION B

T>Δt>tp

Race condition is nothing but toggling of values...this toggling cannot be used if it toggles more in the clock period... i.e it occurs when the time period of the clock pulse is greater than the propagation delay of the flip flop so answer will be

T>Δt>tp conditions must be met to avoid race around problem.

where T=the time period of the clock pulse is greater

tp= propagation delay of the flip flop

Comments

Here individual terms are not defined, then how shall we able to understand which option to choose ??
