You are to generate the first 20 output bits of GPS PRN #1. Initialize the G1 and G2 lfsr registers with all 1s. The feedback and output connections for PRN #1 are shown below. In the figure below note that the circles with + symbols in them represent modulo 2 arithmetic. Ex. mod(3,2) = 1 and mod(4,2)=0 with matlab
