On each pair of line of line 111 and mirror image composite transposition loop wire 121, the useful sense received is opposite.I.e. main composite transposition ring
Line 111 receive signal+, and same instant mirror composite transposition loop wire 121 receive signal-.Wherein mirror image composite transposition loop wire 121
On the signal that receives connected due to its mirror image, signals reverse, be changed into receiving signal+131, make signal be changed into equidirectional signal+.
So it is added by the way that two composite transposition loop wires are in parallel, (signal+)+(signal+)=signal 2+132, i.e. useful signal adds nearly 2
Times.
Therefore it is added by parallel connection, (signal+)+(signal+)=signal 2+132, the signal 2+ in parallel being added received, and simultaneously
Connection is added, and (interference+)+(interference -)=disturbed zero 142, the disturbed zero in parallel being added received, delivers to speed-position detection decoding jointly
In the mixed signal of device 15, signal to noise ratio can significantly increase, and by actual test, signal to noise ratio can increase 40-50db.
