Abstract: PURPOSE:To increase the searching accuracy for a fualt, by setting the number of the space continuities even, for a pseudo random code series and then converting the said code series into the CMI (coded mark inversion) code series to carry out an exclusive OR operation to the repeating point designating pulse. CONSTITUTION:For the artificial random code series PN supplied from an pseudo random code generator PNG, the space continuous number is counted by a space continuous number control circuit ZCC to give the control so as to make the number of space continuities even. Thus a binary code series CI is obtained. Then a CMI code conversion is applied to the series CI to produce a CMI conversion output series CO. Then an exclusive OR operation is carried out through an exclusive OR circuit EXOR between the series CO and a repeating point designating pulse RAP to produce a transmission code series S. The series S is transmitted through a repeating transmission line. The repeater produces an identification output code series DR from a reception code series R. Then a multinomial division of 1/(X+1) is carried out with a clock frequency 2f0 and through a multinomial division circuit DC, and the band pass filtering is carried out by a BPF. Thus a transfer signal B is obtained.
