Title: Duplex amplifier particularly for interphone
IPC: H04M9/08
Filed: 1980-09-26
Abstract: Duplex amplifyer particularly for interphone with a transmission channel and a receiving channel connected in common to a dual track communication line for duplex traffic in both directions and in the same frequency band. The output (R; F) of the transmission channel is connected on the communication line (KL) to a point (P; G) at the input of the receiving channel. This is achieved through a resistive network (R15-R21; R100-R103), by means of which an amplitude equalization may be achieved between the signals coming out of the transmission channel and the signal entering the receiving channel. Thus, the corresponding signals cancel each other while useful signals which do not correspond may be fully processed. The receiving and transmitting channels are opened when not in operation and dampened in the low frequencies of the transmitting frequency ranges. During operation, the dampening of the corresponding channel is suppressed.
