Moreover, a hysteresis range may be specified to ignore any
spurious transition that does not exceed the boundaries of the
hysteresis interval. In Figure 3,

c2d
−
(1, 2) measures the time
interval separating the rising edge of the clock (trigger) from the
first negative transition of the data signal. Similarly,

c2d
+
(1, 2)
measures the time interval between the trigger and the next
transition of the data signal.
