What is "hazard" in a combinational logic circuit, and what is one type?
Correct! Well done.
Incorrect.
The correct answer is A) A hazard is a temporary, unwanted change (glitch) in the output of a circuit caused by different propagation delays along different paths; a "static hazard" occurs when the output should remain constant but momentarily glitches during an input transition
Correct Answer
A hazard is a temporary, unwanted change (glitch) in the output of a circuit caused by different propagation delays along different paths; a "static hazard" occurs when the output should remain constant but momentarily glitches during an input transition
Because different signal paths through a circuit can have different delays, an output that should logically remain stable during a transition might momentarily glitch (a hazard); these can be eliminated by adding redundant logic terms identified via K-maps.
