基于抗锯齿和抗镜像滤波器的低噪声、低失真设计

In any digitizing system, antialiasing and anti-imaging filters are used to prevent the signal frequencies from “folding back” around the sample frequency and causing false (or alias) signals from appearing in the signal we are attempting to digitize. Very often, these filters must be very complex, high order analog filters in order to do their job effectively.
