Abstract of WO 9104611 (A1) System for converting a PCM input signal with uniform noise spectrum, comprising a series of digital words each of K-bits appearing with a predetermined repetition frequency, into a PCM output signal with a non-uniform noise spectrum comprising a series of digital words each of L-bits, L being smaller than K. The...

Abstract of NL 9101155 (A) Method for code acquisition in a satellite receiver. The biphase-modulated high-frequency carrier transmitted by a satellite is converted via a fixed local oscillator frequency down to the baseband, whereafter the baseband signal is fed via a bandpass filter, which has an adequately broad pass band to allow the...

Method and device for filtering a digital signal with the aid of an Mth order finite impulse response filtering with a fractional delay d which is a fraction of the sampling period associated with the digital signal, in order to obtain an interpolated value. This involves predetermining (M+1)/2 window weights wk of a window function which is...

Method for detecting a similarity in shape between a first and a second sampled signal fragment. The method comprises the steps of: formation of a first fragment function from the first sampled signal fragment by means of inverse interpolation, definition of a domain interval, for example the time interval, by searching for the second sampled...
