  • Patent number: 4891801
    Abstract: A terminal is provided for transmitting data over a bidirectional analog channel with echo cncellation coupled to the reception timing, wherein, between an emission circuit and a reception circuit coupled to a bidirectional line by a hybrid coupler, an echo canceller synthesizes an estimated echo from samples of an analog emitted signal, sampled at the same frequency as the received signal, the sampling frequency being controlled by the reception circuit, which is not synchronous with the emission circuit. Such a terminal requires no interpolation filter at the input of the reception circuit and makes possible optimum coupling of the echo canceller with an equalizer.
