Synchronous & Asynchronous Counters

Inside this lesson

Explain how cascading T flip-flops produces a binary ripple counter
Trace the count sequence of a multi-bit ripple counter bit by bit
Identify the propagation delay problem inherent to asynchronous (ripple) counters
Describe how synchronous counters eliminate ripple delay by sharing a common clock
Design a MOD-N counter for counting sequences where N is not a power of 2
