This paper introduces the new class of random processes, - the class of periodically correlated random processes with probabilistic descriptions, functionally dependent within a period. It presents the examples of signals (gas consumption, ambient temperature, considered within comparatively prolonged time intervals, - a season, year), which can be described by using this class of processes. Some...
Consideration of spectra analysis planning in measuring gas consumption based on spectral characteristic changes of random measuring medium process is made. The experimental result are suitable for optimal values of information packets N=2048 and cutting-off point for smoothing correlation window L=512. This value ensures effective signal processing with method based on spectral characteristic changes...
