Why does the procedure produce a glitch in Asynchronous Counters?

Answer 1

Asynchronous counters, often referred to as ripple counters, can produce glitches due to the propagation delay inherent in their design. When a flip-flop changes state, it may take a brief moment for this change to propagate to subsequent flip-flops, leading to a situation where not all flip-flops update simultaneously. This can create temporary incorrect outputs, or glitches, as the counter transitions between states. The cumulative effect of these delays can result in unintended counts or erroneous states during transitions.
