In a static-1 hazard, the output of a combinational circuit may momentarily do what even though it should remain at logic 1?

  • ARemain permanently LOW
  • BDrop briefly to logic 0
  • COscillate indefinitely
  • DBecome high-impedance
Report an error
Correct Answer: B. Drop briefly to logic 0
Explanation: A static-1 hazard is an unwanted 1→0→1 glitch caused by unequal propagation delays along different logic paths.
