Abstract: A device for testing an analog-to-digital converter providing a digital signal at a given sampling frequency, comprising a unit for providing a test signal to the converter, the test signal being a periodic signal comprising frequency components only at a fundamental frequency and at harmonics of the fundamental frequency, the fundamental frequency being a multiple of one quarter of the sampling frequency; a filter capable of receiving the digital signal and of rejecting the fundamental frequency to provide a filtered digital signal; and a unit capable of receiving the digital signal and the filtered digital signal and of providing a signal representative of the ratio between the effective powers of the digital signal and of the filtered digital signal.

Abstract: A circuit is disclosed for the transmission of digital signals on a bifilary line, especially a telephone line. The circuit disclosed is a so-called S interface circuit which has to produce digital signals within certain set limits. The proposed circuit uses four differential amplifiers, each controlling an output transistor (N-channel MOS transistors and P-channel MOS transistors). The amplifiers receive feedback to maintain the overvoltages within acceptable limits. The invention applies especially to the setting up of integrated service digital telephone networks.

Abstract: A self-protected divider bridge in an integrated circuit comprising a P.sup.- substrate, a N.sup.- well, a P region forming a resistor, diffused in said well. A first and a second outmost contact and an intermediate contact are formed on the diffused region. A pad connected to the first contact receives an external voltage higher than the supply voltage of the integrated circuit. The reference potential of the integrated circuit is connected to the second contact and the substrate. A third contact formed on the well close to the first contact is connected to the first contact, and a fourth contact formed on the well close to the second contact is connected to the second contact.
