Step 1

The initial state of the register is given as 1 0 1 1, which means that stage A is 1, stage B is 0, stage C is 1, and stage D is 1. To compute the output sequence, we need to determine the feedback connections and the output bit. Looking at the diagram, we see Show more…

A four-stage linear feedback register is shown in Fig. 2. Suppose that the initial state of the register is 1 0 1 1. Compute the output sequence generated by this shift register. What is the period of the output sequence? Also, compute the time-autocorrelation function of the output sequence over one period. Modulo-2 adder Output Clock Figure 2: Linear feedback register 2.
