Abstract

An algorithm used in a finite-memory digital filter to estimate the low-frequency component of an output signal error in a laser gyroscope is described. In practice, this error component is called a drift, whereas its slow variation is said to be the drift instability. An important peculiarity of this algorithm is its greater level of high-frequency attenuation compared to the widespread filters based on the arithmetic mean algorithm. The frequency properties of these filters are compared.
