    摘要: A process and a circuit for carrying out the process for adapting coefficients in a modem equalizer comprises a memory cell for storing a coefficient, an adapter receiving the output of the cell and providing a first signal having a first correction, and an adder receiving the first signal and providing a second signal to the cell. The adder also receives a value k much smaller than 1 having the sign provided by a comparator comparing an initial value of the considered coefficient and its current value.

    摘要: A circuit for transmitting and receiving communications. The circuit includes a transmit block, a receive block, and an echo canceller, coupled to the transmit block and to the receive block, for determining an echo signal and subtracting it from the received signal, the determination of the echo signal involving a predetermined number N of coefficients calculated at the beginning of each of the communications in an initialization phase. The circuit periodically updates during communication a restricted group of coefficients chosen from among the most significant coefficients. The present invention also relates to an echo cancellation method.

    摘要: A digital phase-locked loop filter in which the incoming error signals are subject to at least one multiplication by a filtering coefficient before being digitally processed at each clock pulse to provide a filtered signal. The PLL filter includes a circuit which decrements the value of the filtering coefficients at each clock pulse during an initial operation period of the filter.
