and Time-Interval Measurement
Time-Interval Measurements
For time-interval measurements between edges of opposite polarity, the errors
caused by dc level errors add rather than cancel as shown in Figure 9-3.
The time errors in locating the leading edge and trailing edge of the pulse
reinforce rather than cancel.
