What Is A Decoupling Capacitor?

Coupling capacitors, on the other hand, provide DC isolation while creating an intentional path for audio, video, RF, and high-speed digital data. Coupling capacitors are often found on high speed interfaces to ensure that any DC potential difference on connected devices does not manifest as ground currents between the devices.
