Quizplus · Accepted Answer

Asynchronous counters are limited in high-frequency applications due to internal propagation delays. Each flip-flop in the counter does not change states simultaneously because each flip-flop's output serves as the clock input for the next flip-flop, leading to a ripple effect that introduces delays.
