This paper introduces the authors' working with the investigation of a dual channel pseudorandom signal generator. Firstly,the theory concerned in this research is briefly quoted. Then,the principle and the construction of this generator are described. To ensure the consistance of signals coming from the two channels and the accuracy of the relative delay time in between them, several measures were adopted during this study. Finally, the results of test and measurement obtained from a prototype generator are given as well.
