Document Type and Number:
Japanese Patent JP7182268
Kind Code:
B2
Abstract:
To provide a power correction device and a power correction method capable of performing noise removal and sound quality improvement with more simple configuration.SOLUTION: A power correction device according to an aspect of the present invention having a first signal line transmitting an input signal supplied from a power source and a second signal line transmitting a circuit direction measuring signal which becomes a pair with the input signal supplied from the power source, comprises: a capacitor for receiving an input of the input signal; a resistor connected to the capacitor; a feedback circuit connected to the resistor; and an inverter circuit connected to the feedback circuit. A power correction method according to another aspect of the present invention removes high-frequency noise with respect to the input signal supplied from the power source and a signal generated due to load fluctuation, and generates a phase delay with respect to a low-frequency input signal component.SELECTED DRAWING: Figure 1
