Abstract :
The design and implementation of a simple tracking digital notch filter for the elimination of sinusoidal interference are presented. The advantages of this filter are its sharp cutoff notch characteristics and the low level of hardware and software complexity for implementation. It is shown that the proposed filter can be implemented in real time on an Intel 8085 8-bit microcomputer system
