Abstract (in Japanese) (See Japanese page) 
(in English) In general, it is known that highly accurate weight measurement is not possible when the measuring
instrument or the object to be measured is shaking. The weight is a DC component, and the AC component is
noise. In this report, we show a method of weight measurement by estimating the frequency corresponding to the
noise using a Hilbert transformer and a variable FIR filter in order to measure the true value of the weight of a
liquid with high speed and high accuracy.
