Аннотация:The solution to the current problem of estimating the frequency of working vibrations of a hemispherical quartz resonator of a solid-state wave gyro (SWG) in the mode of switching information and control signals has been considered. For a continuous information retrieval process, an algorithm for finding the frequency has been successfully developed, but in conditions of switching information and control signals it is not operational. In the switching mode, the time interval for observing signals is limited to a few periods, which complicates the signal processing algorithm.
