    Abstract: A receiver for a digital data transmission device for receiving a digital signal and comprising a free sampler physically taking samples rk of a received signal r(t) at a frequency at least equal to twice the received signal spectrum maximum frequency. A digital interpolator allows to derive a sequence of samples Xk calculated from said physical samples, according to a tuning parameter null. An equalizer adjustable to a set of equalization parameters e allows to process said interpolator output samples Xk. A computing unit simultaneously provides, in a single processing, values of null to the digital interpolator and values of the equalization parameters e to the digital equalizer. The invention also provides a method for digitally processing a received signal in a digital transmission device.

    Abstract: The amount of charge passing through a measurement resistor connected to a rechargeable battery is measured by integrating in an analog manner an overall current. This overall current is equal to the sum of the resistor current and of a reference current that selectively takes one of two opposite values. The results of the integration are compared with a reference voltage, and one of two opposite values of the reference current is selected depending on each result of the comparison. The number of times where the positive opposite value of the reference current is selected furnishes an indication on the amount of charge during the integration time.

    Abstract: A pulse-width-modulated signal is generated out of a sampled reference signal. The least significant bits of a sample of the reference signal are stored in a comparison register. At the same time, a check is made in a test circuit to find out if the sample considered corresponds to a maximum amplitude of the reference signal. If this is the case, an overflow bit is given. The overflow bit and the least significant bits of the sample considered are then linked together to obtain a comparison word. The comparison word is compared with a number given by the counter to generate the pulse-width-modulated signal.
