______ counter is a cascaded arrangement of flip-flops where the output of one flip-flop drives the clock input of the following flip-flop.
Answer: A
A ripple counter is a cascaded arrangement of flip-flops in which the output of one flip-flop drives the clock input of the next, so the change ripples through the chain. In a synchronous counter all flip-flops share one clock. A ring counter is a shift register whose last output is fed back to the first input. 'Cascaded counter' is not the standard name for this arrangement. It is called a ripple counter because the change in one stage moves on, stage by stage, like a ripple, and so it is also called an asynchronous counter.
