<p>PROBLEM TO BE SOLVED: To provide a complementary signal inverted connection correcting circuit for correcting the polarity of complementary signals which are transmitted through a balanced transmission line. SOLUTION: This circuit is provided with a conversion means for inputting the complementary signals and converting them to a single signal, a first frame synchronization means 5 for detecting the frame pattern of the positive polarity of the single signal and outputting a positive polarity detection signal, a second frame synchronization means 7 for detecting the frame pattern of the negative polarity of the single signal and outputting a negative polarity detection signal and an inversion circuit 9 for turning the single signal into an output signal, when the positive polarity detection signal is active and turning the inverted signal of the single signal to the output signal when the negative polarity detection signal is active.</p> |
