Abstract
A new system for filtering the output of rectifiers or the commuttator ripple from generators is discussed, giving the mathematical design and showing the superiority in practical results as compared with standard systems. The system is based on the superposition of a current which has been shifted in phase by means of a wave-filter with one not displaced in phase. The method is also applicable to frequency doubling.
