Bypass Capacitor (Noun)
Meaning
A capacitor that provides low impedance over certain (high) frequencies.
Classification
Nouns denoting man-made objects.
Examples
- The schematic diagram shows a bypass capacitor connected between the power supply and ground to filter out high-frequency noise.
- A high-value electrolytic capacitor is often used as a bypass capacitor to provide low impedance over a wide frequency range.
- In audio circuits, a bypass capacitor is used to couple the audio signal while blocking DC voltage.
- The bypass capacitor helps to decouple the power supply lines from the high-frequency noise generated by the digital circuitry.
- Bypass capacitors are commonly used in high-frequency filter circuits, such as those found in radio frequency amplifiers and switching power supplies.
