The proposed filter eliminate undesirable harmonic from periodic signal. The proposed approach eliminates all harmonics component from periodic signal and it requires only knowledge of the frequency of the fundamental component. Adaptation process adjusts weights to exactly match amplitude and phase of fundamental frequency component and the outputs of the filter is a harmonics replica and are subtracted from the original composite waveform to eliminate them. The bipolar waveforms are roughly analyzed. The simulation results shows that the method can effectively eliminate undesirable harmonics and result in low(less than one percentage) total harmonic distortion (THD).
