Noise rejection for mixed signal in data acquisition system
Shan He · Microcomputer & its Applications · 2010
It is a problem for circuit designer or layout engineer that how to reduce noise as low as possible in data acquisition circuit for mixed signal.At first, enumerate the various factors that bring noise in typical system of analog and digital signal mixed.Then, analyze the most primary influencing factors detailedly.Thirdly, put the specific method and measure to reduce noise aiming at each work flow, they improve system performance effectively.At last, an example design is brought out basing on aforementioned opinion.
