Methods of hardware analysis of non-stationary processes active spectrum

The purpose of this paper is to expose an active spectrum real time analysis main point. We use the meaning about adjusted time. As a result we propose a method of non-stationary processes active spectrum hardware analysis, and we show a possibility of creation of such parallel type analyzer, whose analyzing narrowband filters are adequate to such processes. These filters are band-pass filters or following one-band modulators, which are similar to known systems of automatic frequency following. Proposed method allows to improve essentially the main engineering factors of known analogous random processes spectrum analyzers. © Allerton Press, Inc. 2008.
