Method of calculation of the weighting coefficients for an analytical digitizer for signal processing and analytical digitizer.

摘要

The analytical digitizer for signal processing, comprises: & br / - a sampler and a digital / analog converter - (2, 3); & br / - a first calculating device (4 to 8, 11 to 19) providing a first component of the signal, consisting of a string of digital values x (t), each value being calculated by adding 2h + 2 values supplied by the converter, after having weighted by respective coefficients a0,.., ah, sh,.., a0 whole, non-zero; & br / - a second calculation device (4 to 8, 21 to 29) providing a second component of the signal in quadrature with respect to the first, consisting of a series of digital values y (t), each value being calculated by adding 2h + 2 values supplied by the converter, after having weighted by respective coefficients b0,.., bh - 1, -, - 1,.., - b0, whole and not zero. & br / application to the radio surveillance receivers, in particular.
