Experiments with Digital Computer Simulations of Pseudo-Random Noise Generators

One of the most useful binary linear sequential machines is the maximal-length linear sequence generator. These are sometimes known as pseudo-noise generators because of certain statistical characteristics of their output. One of the more tedious problems in the application of -these generators has long been the calculation of the time displacement of the vectors constituting the output bit stream. In the past, this has been accomplished by programming a computer to simulate the generator and counting steps to the wanted output vector. We show in this paper a much simpler solution to the problem which can be accomplished by means of simple hand calculations.
