SUMMARY.
a. The time constant indicates how rapidly current or voltage in
a circuit can change. The time constant is also a factor in
determining the amplitude and shape of the output pulse. (Paragraph
35a)
b. The pulse reference periods are the rise time, duration time,
and decay time. (Figure 25)
c. A shorttime constant can be defined as less than oneseventh
of the value of a given reference period. (Paragraph 35h)
d. A longtime constant can be defined as more than 7 times the
value of a given reference period. (Paragraph 35i)
e. An equivalent time constant is less than 7 times but more than
oneseventh of the value of a given reference period. (Paragraph 31a)
f. A series RC circuit is called a highpass filter when the
output is taken across the resistor. A series RC circuit is called a
lowpass filter when the output is taken across the capacitor.
(Paragraph 31b)
