A common method of avoiding race-around in a JK flip-flop is to use?

  • AA master-slave or edge-triggered flip-flop
  • BA larger supply voltage only
  • CAn OR gate at the output
  • DA resistor in series with every input
Report an error
Correct Answer: A. A master-slave or edge-triggered flip-flop
Explanation: Master-slave or edge-triggered operation restricts the effective state transition and prevents repeated toggling during one clock interval.
Reference: Standard digital electronics: JK flip-flops
