When counters are referred to by circuit design, they are called

• A. Ripple
• B. Synchronous
• C. Ripple or Synchronous
• D. Asynchronous

Answer: (C)

Counters in digital design are categorized by how their flip-flops are driven and clocked. There are two main architectural styles: ripple counters, where each flip-flop’s clock comes from the previous stage and the counting ripples through the chain, and synchronous counters, where all flip-flops are driven by the same clock and a combinational network determines the next state. Designers often discuss counters by these architectural forms, so the common way to refer to counters is as either ripple or synchronous. The other single-term options only describe one style or refer to the asynchronous family without acknowledging the synchronous approach, so they don’t capture the full way counters are described in circuit design.
