Paragraphs
PRF is the pulse repetition frequency in pulses per second (pps).
Suppose, for example:
t 1 = 10 microseconds
t 2 = 990 microseconds
K | = | 0.55 |
|
|
|
|
|
|
PRF | = | 1000 pps |
|

To find K, assuming | = | 2 | kilohms | and | tl=10micro - | |||
s e c o n d s : R o /tl = 2 / 10° | = | 0.2. Location | 0.2 | on the | ||||
X axis | of | the graph | shown | as Figure | and | reading |
K where X and Y axes intersect the unmarked curve. If
the | ratio | of R o /tl were | greater | than 1, | multiply | the |
X | and Y | axes by 10, | and use | the curve | marked | ”Ro/ |
t1 and K each X10”. |

(t2) and | a pulse repetition frequency (PRF) of 1000 pps, |
tl would | be 990 microseconds. Thus T o/t1 would be |
approximately 0, and from the graph it is seen that K is approximately 0. The expression would then reduce to
