Correlation method for impulse-response measurements using matched filters†
ANCA TOMESCU, F. M. G. Tomescu · International Journal of Control · 1970
In this paper is given a comparative study of the correlation methods for determining the impulse-response of a pseudo-linear system, using pseudo-random signals. As a result a new method is described in which a filter matched to the periodic pseudorandom binary signal is used to obtain the needed correlation function.
