The counter, as shown in the schematic, is six D-type flip-flops connected in cascade, with feedback to the input of the first in-the-series flip-flop via a two input exclusive or gate. This results in a pseudo-random sequence of zeroes and ones at the serial output terminal. There are six parallel outputs and one serial output. What I want to do is to select two outputs from the seven available outputs that will produce a sequence of pairs of zeroes and ones with the greatest possible randomness. So the question is, which pair of outputs should I choose, and why?
