Noise management using capacitors makes use of their characteristics of high impedance in low-frequency ranges and low impedance in high-frequency ranges. A capacitor is connected between a power supply line and grounding to prevent noise propagation to the subsequent circuit (Load side) by passing the noise to the grounded side.
If the frequency of the noise is fixed, it is possible to obtain a significant noise reduction effect, as long as the self-resonant frequency can be adjusted to match the noise. In order to adjust the self-resonant frequency, select a capacitor with an electrostatic capacitance that matches the noise.
This capacitor is sometimes referred to as a bypass capacitor because it bypasses noise to the ground, or as a decoupling capacitor because it separates the circuits of the previous and latter stages. This basic characteristic of capacitors can be used for noise management because most noise is from high-frequency AC.
The noise reduction circuit is based on the observation that noise is always disturbing in intervals when music stops. It will attenuate the signal output by about 45 dB, when the musical signal input is null or very weak.
Capacitors typically integrate between the GND and noise path. In effect, these can transmit high-frequency noise either to the ground connection or power supply. At the same time, low frequencies pass through. Therefore, this results in the capacitor bypassing the noise current. (Capacitors integrate between the ground line and noise path.)
When noise enters a DC current flowing inside an electronic circuit, voltage fluctuations could occur, leading to IC malfunctions. To deal with this, capacitors are widely used to remove noise. This is because a capacitor functions as the simplest noise filter by blocking DC current while allowing noise to pass.
