Transmission system with balanced bridge to prevent low frequency cross talk |
摘要 |
Transmission system for transmitting signals modulating a carrier between two main stations via parallel coaxial lines the inner conductors and the non-earthed outer conductors of which are connected to the earthed main stations via capacitors. The main stations contain low-frequency signal sources which in parallel with direct-current supply sources are connected to the supply current loop for the repeaters included in the coaxial lines. The low-frequency cross-talk due to the low-frequency signals is suppressed by means of compensating circuits.
