ABSTRACT
This chapter discusses the waves more commonly encountered within systems. These waves are not as pure as drawn; some parasitic oscillations from the transformer and other components will be superimposed on the waveforms. In real-world observation, these waveforms have rise and fall times due to parasitic effects; however, they are shown in the text as pure step functions that are impossible to achieve. Voltage and current spikes are one of the common waveforms or noise sources encountered in electronic circuits. Voltage and current spikes are one of the common waveforms or noise sources encountered in electronic circuits. Voltage spikes are short-duration impulses in excess of the normal voltage. The pulse is similar to the quasi-square, but with pulses in the same direction as for the spike. Lightning strikes can also create voltage spikes, even when the discharge event may have occurred a mile away.
