Section V. SUMMARY AND REVIEW
9.
SUMMARY.
a. Waveshapes that do not follow the conventional pattern of the
sine wave are called nonsinusoidal waves.
b. An aperiodic wave is a wave which appears at irregular
intervals or only once.
c. A period wave is a wave that is repeated at constant
intervals.
d. Nonsinusoidal waves can be analyzed by either the frequency
response method of analysis or the transientresponse method of
analysis.
e. A steady state is a period when there is no change in voltage
or current.
f. The frequencyresponse method analyzes a waveform by
determining the number, amplitude, and frequency of sine waves
required to reproduce it.
g. The rate at which a waveform is repeated is known as
repetition frequency, and is equal to the frequency of the
fundamental sine wave required to produce it.
h. The second harmonic is equal to twice the frequency and half
the amplitude of the fundamental frequency.
i. When forming a waveshape, the maximum number of harmonics that
must be included varies inversely with the pulse width.
j. The transientresponse method analyzes the response of a
circuit to nonsinusoidal voltages.
k. A transient is a brief change in voltage or current.
l. Transient time is the period of time during which the
transient occurs.
m. A square wave consists of a fundamental frequency and its odd
harmonics.
n. A rectangular wave consists of a fundamental frequency and
establish the desired reference level.
o. A sawtooth wave consists of a fundamental frequency and its
even and odd harmonics.
