Question

Explain the following situations:
I. There are two sketches in 3A and 3B. They bothhave the trigger level zero, but one has a positive trigger slopeand the other has a negative trigger slope.
II. The appearances of sketches 4A, 4B, and 4C all havea positive trigger slope, but the trigger level of 4A is zero, thetrigger level of 4B is positive, and the trigger level of 4C isnegative.

II. The appearances of sketches 4A, 4B, and 4C all havea positive trigger slope, but the trigger level of 4A is zero, thetrigger level of 4B is positive, and the trigger level of 4C isnegative.

Explanation / Answer

I. Since the trigger levels are ero for both, the plotsbegin at (0,0). Now, the slopes determine how the plots of y changewith varying x. slope = y/x   So, the negative one has y decreasing withincreasing x and the other, positive one has y increasingwith increasing x. II. The trigger levels determine where the plots begin (y-value) at zero value of x. So, slopes being positive each y-plot increases withincreasing x. However, 4A begins at origin (0,0), 4B begins at y>0for x=0, 4C begins at y<0 for x=0.
