ノイズキャンセル装置

摘要

PROBLEM TO BE SOLVED: To provide a noise canceller capable of removing noise by a simple configuration.;SOLUTION: A noise canceller comprises: a first connection line which connects an input terminal for allowing the input of an electric signal obtained by converting sound to an output terminal for outputting the electric signal; a first resistor arranged on the first connection line; a second connection line which is connected, on the first connection line, from a first connection provided between the first resistor and the output terminal to a ground; a first capacitor arranged on the second connection line; a third connection line which is connected, on the first connection line, from a second connection provided between the first connection and the output terminal to the ground; and a second resistor and a second capacitor which are arranged, on the third connection line, in parallel to the first capacitor.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
