Abstract
In this paper we propose a new time domain method for separating a periodic interference signal component from speech signal. The method handles also such cases in which the amplitude of a periodic interfering signal fluctuates and when the speech signal occasionally is located in the same frequency band as the interfering signal. The method is applied with success to the filtering of electromagnetic interference produced by a TDMA-based system from speech signal
