Abstract
The invention concerns a power separating filter for high frequency digital data transmission channel and low frequency telephone analog signal channel, simultaneously transmitted on a subscriber loop comprising a two-wire telephone line (2) having a complex characteristic impedance, wherein the low frequency channel includes a passive output equalizer (24) comprising a resistor and an inductance in parallel, adapting impedance to the characteristic impedance, and an active equalizer (22), compensating resistive losses of the passive equalizer (24), so as to transmit, with slight losses and under the characteristic impedance, the telephone signals between the telephone line (2) and the telephone exchange (1) or the subscriber station (3) without inducing statics in the line (2).
