Harmonic content elimination
Principle of the new method of filtering of a signal containing basic frequency component, harmonic components and DC component is presented. Method of elimination of DC component as well as second and third harmonic component from input signal is given in detail. Presented experimental results based on input signal with high amounts of DC and harmonic content show very good agreement between waveforms of input and output basic frequency component. Very small time delay of the output signal is one of basic qualities of the method, which has not been possibly to realize by other methods.
