ANSLUTNINGSUTRUSTNING FOR ETT BERFREKVENS-TELEFONSYSTEM |
| 摘要 |
The invention relates to terminal equipment for a carrier current multiplex system with a half echo-suppressor and a channel modem. The attenuator which is inserted in the transmission chain is disposed after a first modulation stage, thereby taking advantage of the propagation time of the filters of the modem to reduce the apparent reaction of the attenuator. |
