Hazards

Load the PSPICE file shaz.sch.

Simulate the circuit and note the glitch in the output waveform.

Use the PROBE zoom features to see the glitch in detail (e.g. use the cursor to locate a vertical strip around the glitch and then View $\to$ Area).

Modify the circuit by adding hazard cover. Simulate again and observe the output waveform.
