DATA SIGNAL TRANSCEIVER CIRCUITRY FOR PROVIDING SIMULTANEOUS BI-DIRECTIONAL COMMUNICATION VIA A COMMON CONDUCTOR PAIR
摘要
Interface circuitry and method for transmitting and receiving downstream and upstream data signals simultaneously via a common conductor pair. The composite signal containing the downstream and upstream data signal components being conveyed by the common conductor pair is isolated, e.g., via signal filtering or buffering, and combined with an appropriately scaled inverse replica of the outgoing upstream data signal to subtract out upstream data signal components and thereby provide the downstream data signal substantially free of any upstream data signal components.
