A static-0 hazard in a POS combinational circuit is an unwanted transition in which the output, ideally remaining 0, may briefly?

  • ARise to 1 and return to 0
  • BRemain permanently at 1
  • CEnter high impedance
  • DToggle only on a clock edge
Report an error
Correct Answer: A. Rise to 1 and return to 0
Explanation: A static-0 hazard is a temporary 0→1→0 glitch caused by unequal propagation delays when the correct steady output should remain LOW.
