Step and Pulse Waves
Step and pulse waves are generated only once from a
circuit. These signals are also called single-shot or transient
signals. A step wave indicates a sudden change in voltage,
which may be the result of turning on an electric switch. A
pulse wave represents a sudden change in signal level
followed by a return to the original level. For example, a
pulse is generated if you turn on a power switch and then
turn off the switch.
A pulse can represent the following information:
•
One bit traveling through a computer circuit
•
A defect or a glitch in a circuit
Figure 1.9 shows examples of step and pulse waves.
