Abstract :
Based on the transfer function, this paper presented a new method of designing digital notch filter in order to eliminate the 50 Hz 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.
