摘要
This paper proposes a howling reduction circuit using analog phase-locked loop (PLL) and active noise control (ANC) circuits. The proposed circuit reduces howling by generating a signal opposite in phase to howling. To make a signal with the same frequency as howling, we employed the PLL circuit. The ANC circuit was used to control the amplitude of the signal. In addition, we employed pseudo-lock avoidance and differential switch circuits to avoid noise generation. The results confirm the effects of howling reduction by the proposed circuit. (C) 2014 Elsevier Ltd. All rights reserved.
