摘要: An isolation circuit for use as a telephone line interface includes at least one pair of capacitors (54, 56) that differentially couple analog transmit (TX) and receive (RX) channels in full duplex communication across an barrier. The are connected the barrier, each or signal is processed to generate respective paired complementary signals. In another aspect, invention can be configured two pairs (31, 33) user device (21) barrier (23) on (23).
