High-frequency vibration suppression: the capacitor used in the high-frequency vibration suppression circuit is called the high-frequency vibration suppression capacitor. In the audio negative feedback amplifier, in order to eliminate the high-frequency self-excitation that may occur in the vibration, this capacitor circuit is used to eliminate the high-frequency whistling that may occur in the amplifier.
