Digital ElectronicsFlip-Flops

Unlike an asynchronous reset, a synchronous reset normally changes a flip-flop’s state?

  • AOnly in association with the active clock edge
  • BImmediately regardless of the clock
  • COnly when power is removed
  • DOnly after the clock stops
Report an error
Correct Answer: A. Only in association with the active clock edge
Explanation: A synchronous reset is sampled as part of the clocked logic operation and therefore takes effect at the relevant active clock edge.
Reference: Standard digital electronics: synchronous reset
