Abstract

Combined correlation differential system for leveling time delays of signals relates to systems of automated control and can be used in apparatuses for protection against radio noise. The system includes two channels of passage of signal from one source, in first of those block of permanent delay is included, and to the second one – block for controlled delay. The system has four correlators each of which consists of connected in series multiplier and leveling filter, four blocks of time delay, two subtraction devices, two amplifiers-transformers, adding device and executive element. Output of block of permanent delay directly and through two blocks of time delay is connected to correlators. Output of second channel is connected to one correlator directly, and throughtwo blocks of time delay is connected to correlators. Output of second channel is connected to one correlator directly and with the other one – through block of time delay, and with input of block of controlled delay output of which is as well connected to two correlators directly and through block of time delay. Outputs of all correlators through subtraction devices and amplifiers –transformers are connected to adding device that through executive element is connected to block of controlled delay. System provides increase of dynamical accuracy and operation speed, this makes it possible to increase quality of correlation radio reception.
