Abstract
In this paper, we propose a new algorithm for the detection of howling signals employing an LMS adaptive notch filter and digital phase locked loop. The main advantages of the proposed algorithm are that it has very low computational complexity and has a short detection delay. Computer simulations are given to demonstrate the performance of this method.
