Optimization of the rearrangement rules of performances of dynamic filters of the second order for spectral analysis of random signals

摘要

The initial relationships for a function of a spectral window for the narrow-dynamic filter of the second order and relative dispersion of an estimation of a spectral density of power measured by correlative-filter method and also generalized expression for the optimal rule of rearrangement of an attenuation coefficient of the filter at linear changing of its center frequency in a band of analysis are obtained.
