Power Supply Noise Reduction - Designer’s Guide
designers-guide.orgMar 10, 2019 · Decoupling is the isolation of two circuits on a common line. The decoupling network is usually a low pass filter and the isolation is rarely equal in both directions. Decoupling is used to prevent transmission of noise from one circuit to another. In the figure a bypass capacitor, C byp, is shown along with the decoupling circuit, L dec and ...
