专利汇可以提供Signal extracting system专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent the malfunction caused by the detouring signal, by inhibiting the output of the analog filter for the facsimile or the like for the period during which from transmission start of the transmission signal to the transient answer end of the analog filter after completion.
CONSTITUTION: Phase signal (a) sent from transmission part 2 of transmission system T is transmitted to the telephone circuit from control part 10 via hybrid 1. Phase matching end signal (b) sent from the partner side is piled on signal (a) through circuit 1 and supplied to analog filter 3 of reception system R to extract signal (b). In this case, signal (d) is deliverd due to the effect of signal (a) and sliced via comparator 8 to be turned to signal (e) which is suppled to counter 9. In this instant, signal (f) is supplied to counter 9. In this instant, signal (f) is supplied to counter 9 from circuit 10 to inhibit the counting action then. Counter 9 delivers overflow signal (g) when the counting reaches the prescribed value
