Abstract
It is proposed that the narrow-band filter in filtering spectrum analyzers be made dynamic, i.e., operate in a transient mode, with the characteristics adjusting according to given laws. The initial ratios are obtained for the optimal synthesis of those characteristics of narrow-band filters used in the direct filtering and the correlation-filtering methods. The problem of optimizing the laws governing the tuning of filter characteristics is formulated.
