Abstract: A decimation filter for converting a train of sigma-delta pulses S(i) in synchronism with a sigma-delta clock (fs) into a train of PCM samples which includes counters (321, 331, 341) driven by the sigma-delta clock (fs) and which is continuously incremented by one during N sigma-delta clock pulses, then decremented by two during N following sigma-delta clock pulses and then incremented again by one during N following sigma-delta clock pulses in order to provide a sequence of incrementation parameter DELTA(n). The decimation filter further includes storages (320, 330, 340) for storing the value of the coefficient C(n) corresponding to the decimation filter transfer function, and incrementers (327, 337, 347) driven by the sigma-delta clock fs for incrementing the storages with the incrementation parameter DELTA(n). Finally, the decimation filter includes computers (323, 333, 343, 327, 337, 347) for deriving from the contents C(n) of said storages and from the train of input sigma-delta samples S(i+n) one Pulse Code Modulation (PCM) sample every 3.times.N input sigma-delta samples according to the formula: ##EQU1##

Abstract: A predictive clock extracting circuit having a first circuit for determining the duration between two consecutive transitions of a multilevel digital signal and a second circuit for generating an SPL pulse at half the duration after a third transition following on two consecutive previous transitions. A phase locked oscillator which is driven by said SPL pulse generates the extracted clock signal which is in phase with the SPL pulse and coincides with the center of the eye intervals of said multilevel digital signal. The system includes a first counter N which starts running in response to the detection of the first transition of the multilevel digital signal. The running stops when the second transition occurs. The result N(i) stored into the first counter N at second transition is therefore representative of the duration between the two consecutive first and second transitions. The preferred embodiment of the invention also involves an up/down counter K which generates a second counter K(i) that is expected to be representative of half the value of the first counter N(i). Counter K is adaptively updated by incrementing its current value K(i) by a fixed factor or, on the contrary, by decrementing its current value K(i) by a fixed damping factor.

Abstract: Methods and systems for analyzing the quality of high-speed signals are provided, wherein a high speed signal is sampled simultaneously a plurality of times during a sampling clock period at each of a plurality of phase rotator positions to generate a plurality of partial values, wherein subset pluralities of the partial values are associated to phase rotator positions. The partial values are combined into a global value which is analyzed to determine a quality of the high speed signal. Phase rotator behavior may also be analyzed to determine signal quality. A best position to lock a phase rotator when determining signal quality may be determined from a graphic characterization of a phase rotator position distribution.

Abstract: A Decimation filter for converting a train of sigma-delta pulses S(i) in synchronism with a sigma-delta clock (fs) into a train of Pulse Coded Modulation (PCM) samples in accordance with the formula ##EQU1## where Cn is the sequence of the coefficients of the decimation filter which corresponds to a determined decimation factor, and the PCM samples being processed by a Digital Signal Processor (DSP). The decimation filter includes a device for storing a digital value representative of the DC component introduced during the sigma-delta coding process, with the digital value being computing by the DSP processor during an initialization phase. The decimation filter further includes a device operating after the latter initialization phase for subtracting the stored digital value from each of the PCM samples so that the resulting sequence of PCM samples appears free of any DC component introduced during the sigma-delta coding. This accurate DC component suppression is achieved without necessitating the use of additional digital signal processor resources from the processor. Preferably, the decimation filter comprises a device for detecting a saturation occurring in the computing of the PCM sample, and responsive to the saturation detection, for transmitting a predetermined PCM sample to the DSP processor.

Abstract: A multiprocessor system includes a plurality of signal processors and a common unit processor. Each of the signal processors is connected to a different source of signals such as voice signals and performs one or more signal processing functions relative to the connected source. The common unit processor performs one or more functions for the signal processors on a shared synchronized basis. A signal processor adapter responsive to a source of clock pulses generates synchronous interrupts applied to the common unit processor and enabling signals in sequence to connect the signal processor in sequence to the common unit processor in synchronization with the interrupts. In addition, the signal processors are provided with ping-pong buffers at their inputs and outputs to enhance throughput.
