Abstract

This paper shows some fundamental study results from the guided noise cancellation technique. Special emphasis is placed on the noise cancellation capability of both series and parallel systems on periodical input sound waves. Theoretically, in each stage, a series noise cancellation system can cancel the fundamental wave and all the odd harmonic waves completely, while a k‐phase parallel noise cancellation system can cancel the fundamental and all the harmonic terms except the k‐th, 2k‐th, 3k‐th, … terms. We also present the experimental results for showing the feasibility of this approach.
