Figure 2-33.—Pulse-repetition time (prt).
Just remember that the pulse-repetition time is the time it takes for a pulse to recur, as shown in
figure 2-34. The duration of time of the pulse (a) plus the time when no pulse occurs (b) equals the total
pulse-repetition time.
Figure 2-34.—Pulse cycles.
The time during which the pulse is occurring is called PULSE DURATION (pd) or PULSE WIDTH
(pw), as shown in figure 2-35. As you will soon see, pulse width is important in pulse modulation.
