Experimental Study of Correlator Filters Not Utilizing a Delay.
Abstract
This work is an application of the methods in obtaining the correlation functions. In particular, the method of correlation without a 'pure' time-delay is presented together with the concept of 'orthogonal filters', which are Laguerre function type filters. Of these filters, the non-symmetric Laguerre type is analyzed and used to realize a practical correlator designed for low frequency signals. The correlator was computer-simulated by the DSL subroutine and the results of the autocorrelation of a 155 Hz sine wave were compared to the results obtained for the autocorrelation of a similar wave in the actual correlator. A detail description of the design of the correlator and of the DSL program used are also presented.
