How would you implement a modulo-10 counter using 4-bit binary flip-flops?

• A. Use a 3-bit counter with gating to 10
• B. Use a 4-bit binary counter with asynchronous or synchronous clear when the count reaches 1010 (10); reset to 0000.
• C. Use a 5-bit counter with clear at 1010
• D. Use a 4-bit counter with modulo-16

Answer: (C)
