Abstract
An exclusive OR of outputs from a plurality of shift stages of an M-series generator is formed, thereby obtaining an M-series which has a desired delay, which in an example is a three bit delay with respect to the output code from the generator. Similarly, outputs from a plurality of shift stages are combined and an exclusive OR thereof is formed to provide another delayed M-series. An exclusive OR of each output from the simultaneously delayed code generator and an output from another M-series generator is formed, thus simultaneously obtaining a plurality of Gold code series.
