DIGITAL FILTER Russian patent published in 2010 - IPC H03H17/02 

FIELD: measurement equipment.

SUBSTANCE: invention is related to digital technology of signals processing and may be used to filter results of weight measurement, values of which are expressed in digital code. Device makes it possible to process (filter) low-frequency oscillations of a priori unknown frequency and amplitude. It is possible to detect value of weight by the first period of analysed (filtered) oscillations that arrived at filter. It makes it possible to detect value of weight not waiting for completion of oscillating process, which practically always occurs in transition from condition of "unloaded scales" to condition of "loaded scales". In its turn, it makes it possible to considerably improve efficiency of weight measurement device.

EFFECT: improved noise immunity and efficiency.
