INSTRUMENTS FOR DETERMINING CORRELATION FUNCTIONS,
Abstract
A brief description is given of a new electromechanical correlator for the calculating correlation and mutual correlation functions. It was developed jointly by the Institute of Automation and Telemechanics (Institut avtomatiki i telemekhaniki) and the Tsvetmetavtomatika Design Bureau (Konstruktorskoye byuro Tsvetmetavtomatika). Two standard RU5-02 servomechanisms are used for information scanning from 160-mm wide diagram rolls. The correlation function of two stationary random processes is carried out by multiplying and integrating two electrical quantities proportional to the parameters under investigation. The integration is carried out on an integrating motoro the number of turns of which is a linear function of the applied voltage. The article presents the block diagram of the electromechanical correlator, detailed technical data, the circuit diagram of the frequency divider block, and an example of correlation function determination, which is compared with the correlation function calculated on an electronic computer. The correlator error does not exceed 15%. The calculation of 30 points of the correlation function from a 1.5-m long recording of a random process required 4 hours of work with a 3 mm/sec speed of advance.
