DEVICE FOR TRACKING ANALYSIS OF ACTIVE SPECTRUM OF NON-STATIONARY PROCESSES

摘要

Device for tracking analysis of active spectrum of non-stationary processes has 3-5 channels of simultaneous analysis, each of those has controlled filter (CF) at control input of which there is control element (KE). To each channel are included connected in series standard frequency discriminator (FD) and stationary smoothening low frequency filter (SLFF) output of which is connected to input of KE. Input of FD is connected to output of CF, this is band filter frequency filter of each of those is equal to active band of respective component of active spectrum, and middle frequency of initial tuning of those depending on needed law of distribution at frequency range of analysis has definite value.
