Abstract:
1. A waveguide apparatus comprising: a first comparator waveguide subsystem comprising an input port A, an input port B, a difference port A−B, and a sum port A+B, wherein said first comparator waveguide subsystem is structured to produce at said difference port A−B a difference signal A−B that is a subtraction of a signal B at said input port B from a signal A at said input port A and produce at said sum port A+B a sum signal A+B that is a sum of said signal A and said signal B, wherein said first comparator waveguide subsystem comprises: a second comparator waveguide subsystem comprising an input port C, an input port D, a difference port C−D, and a sum port C+D, wherein said second comparator waveguide subsystem is structured to produce at said difference port C−D a difference signal C−D that is a subtraction of a signal D at said input port D from a signal C at said input port C and produce at said sum port C+D a sum signal C+D that is a sum of said signal C and said signal D, wherein said second comparator waveguide subsystem comprises: a third comparator waveguide subsystem comprising an input port A−B connected to said difference port A−B of said first comparator, an input port C−D connected to said difference port C−D of said second comparator, a difference port (A−B)−(C−D), and a sum port (A−B)+(C−D), wherein said third comparator waveguide subsystem is structured to produce at said difference port (A−B)−(C−D) a difference signal (A−B)−(C−D) that is a subtraction of said difference signal C−D from said difference signal A−B and produce at said sum port (A−B)+(C−D) a sum signal (A−B)+(C−D) that is a sum of said difference signal A−B and said difference signal C−D, wherein said third comparator waveguide subsystem comprises: a fourth comparator waveguide subsystem comprising an input port A+B connected to said sum port A+B of said first comparator, an input port C+D connected to said sum port C+D of said second comparator, a sum port (A+B)+(C+D), and a difference port (A+B)−(C+D), wherein said fourth comparator waveguide subsystem is structured to produce at said difference port (A+B)−(C+D) a difference signal (A+B)−(C+D) that is a subtraction of said sum signal C+D from said sum signal A+B and produce at said sum port (A+B)+(C+D) a sum signal (A+B)+(C+D) that is a sum of said sum signal A+B and said sum signal C+D, wherein said fourth comparator waveguide subsystem comprises:
