Choose capacitor types to optimize PC sound quality
A key challenge to designers of audio subsystems that must conform to Windows Vista requirements may be choosing coupling capacitors. These devices' capacitance varies with the voltage across them and introduces audio distortion. To minimize the effect, start by understanding the interactions among the dielectric material, voltage rating, device size, and voltage coefficient. Then, get ready to make trade-offs. |
