they can appear within the jitter interval as shown in Figure 6-12. An event

function model allows us to vary the number of events in an interval. The num-

ber of events in an interval ranges between and .

An event function counts the number of events in an interval, so it is a piece-

wise constant function with unit steps—each step adds one more event to the

system. We can also define a periodic with jitter event model as

, (EQ 6-7)

. (EQ 6-8)

We can also define a minimum distance function δ

min

(N) and maximum

distance function , which define the minimum and maximum distance

between N = two or more events. We ...
