FILTERING DEVICE AND FILTERING METHOD

Title:

FILTERING DEVICE AND FILTERING METHOD

Document Type and Number:

WIPO Patent Application WO/2018/163364

Kind Code:

A1

Abstract:

The present invention provides technology capable of efficiently removing noise while performing detection in a short time using numerical phase detection with respect to an alternating-current signal. A detection unit 1 performs numeric phase detection with respect to an alternating-current signal. Consequently, a plurality of detection results corresponding to an accumulated number of vibrations in the numerical phase detection can be acquired. A linear combination unit 2 performs a linear combination of the plurality of detection results using a linear coefficient corresponding to a filter characteristic. This makes it possible to filter the alternating-current signal.
