Abstract: An electronic device (ED) is intended for generating a local oscillator signal having a chosen frequency FLO from a main signal outputted by a voltage-controlled oscillator (VCO) and having a fundamental frequency FVCO and harmonics thereof. This electronic device (ED) comprises a frequency division means (D1, D2) arranged to divide the frequency of a signal by a chosen factor N and a filter means (F1, F2) arranged to select a chosen Mth order harmonic of a signal, these frequency division means (D1, D2; D) and filter means (F1, F2) being arranged to process the main signal in common to output the local oscillator signal with a chosen frequency FLO equal to MxFVCO/N.

Abstract: The present invention relates to a device for connection of a digital apparatus on a telephone line, comprising a line interface (6) which is connected to the telephone line, and a control circuit (8) to control this line interface (6), which can detect a fault in transmission through the line, the line interface (6) and the control circuit (8) each comprising at least one memory (42, 44, 62,64), and exchanging digital information via a galvanic connection.

Abstract: The present invention relates to a method for synchronisation of at least one first device or apparatus (6) with at least one second device or apparatus(7), comprising respectively a first (8) and a second (10) counter modulus n, and which are designed to exchange data by means of a galvanic connection.

Abstract: A telephony device includes a rectifier bridge (GB) intended to be connected to a telephone line and to supply a rectified line current, an interface module (INT) permitting the transmission of signals in the direction of the telephone line and supplying an information signal (Iin), and an amplifier (AGC) whose gain is proportional to the value of a control current (Icnt) supplied by a control module (CNT). The control current (Icnt) is proportional to an exponential of a linear equation of the inverse of the value of the information signal (Iin) in order to compensate for the attenuation which the signal has undergone during its transport through the telephone line.
