LESSON OBJECTIVES
When you have completed this lesson, you will be able to:
a. Use time constants to determine the outputs, at any specified
time, of various RC and RL circuits.
b. Analyze the input and output waveforms of RC and RL circuits
to determine the type of filtering action taking place.
c. Distinguish between differentiating and integrating circuits.
d. Select the component across which the differentiated and
integrated waveforms appear when given the circuit time constant.
1.
WAVEFORMS.
a. Types. A waveform can be described as any rise or fall of
voltage or current over a finite period of time. Waveforms that do
not follow the conventional pattern of the sine wave are called
nonsinusoidal waveforms. Various nonsinusoidal waveforms are
produced in electronic circuits.
(1) Aperiodic. A nonsinusoidal waveform that appears at
irregular intervals.
(2) Periodic. A periodic waveform is any waveform that is
repeated at constant intervals. Unless specifically referred to as
aperiodic, all waveforms discussed will be periodic waveforms.
