Los Angeles, California USA
March 31-April 02
ISBN: 978-0-7695-3507-4
Based on the transfer function, this paper presented a new kind of design method of digital filter in order to eliminate the 50Hz noise. The filter was realized by software implementation in VC++ environment, and, simulated by MATLAB. Experimental results show that algorithm could remove power-line interference effectively, and its operation was simple and applicable.
