Chapter 6
Filters
Certain types of circuits are found in most electronic devices used to process alternating current (AC) signals. One of the most common of these, filter circuits, is covered in this chapter. Filter circuits are formed by resistors and capacitors (RC), or resistors and inductors (RL). These circuits (and their effect on AC signals) play a major part in communications, consumer electronics, and industrial controls.
When you complete this chapter, you will be able to do the following:
- Calculate the output voltage of an AC signal after it passes through a high-pass RC filter circuit.
- Calculate the output voltage of an AC signal after it passes through a low-pass RC circuit.
- Calculate the output voltage of an AC signal after it passes through a high-pass RL circuit.
- Calculate the output voltage of an AC signal after it passes through a low-pass RL circuit.
- Draw the output waveform of an AC or combined AC-DC signal after it passes through a filter circuit.
- Calculate simple phase angles and phase differences.
