Capacitor Voltage Transformer (CVT Or CCVT)
Coupling Capacitors are only used for coupling high-frequency communication signals and they are equivalent to the capacitive part of CVT. Series connected capacitor elements, housed in porcelain shells, each hermetically (in an airtight manner) sealed, are referred to as capacitor sections. The dielectric of the capacitor elements is made up ...
Introduction to Coupling Capacitor
A capacitor which is used to link one circuit''s AC signal to another circuit is referred to as a coupling capacitor. Blocking the DC signal and allowing the AC signal from one circuit to another is the main feature of this capacitor. In different circuits where AC signals are used for output, these capacitors are used, while DC signals are simply used to supply power …

Understanding AC Coupling Capacitors at Multi-Gbps Data Rates
AC coupling capacitors are frequently used in multi-gigabit data links. Many current data standards require AC coupling (for example PCIe Gen 3, 10 Gb Ethernet, and so on). In addition, there exist incompatible common mode voltages between drivers and receivers, for which AC coupling is the simplest means to solve this problem. Designers may look in vain for …

Coupling & Bypass Capacitors
2.0 - Coupling Capacitors. The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used. Since DC carries no audio ...

Due to their DC-blocking characteristic, coupling capacitors are widely used to prevent potentially harmful charge buildup at the electrode–tissue interface. Although the capacitors can be an effective safety measure, it often seems overlooked that coupling capacitors actually introduce an offset voltage over the electrode–tissue interface as well.
