A Note on Sequences Generated by Clock Controlled Shift Registers

In this paper the linear feedback shift registers are determined that can generate the output sequence of two types of clock controlled shift registers suggested by P. Nyffeler. For one type of clock control sufficient conditions are given which guarantee that maximum linear complexity is obtained. Furthermore, it is shown that the randomness properties for sequences of maximal linear complexity depend on clocking procedure.
