摘要： A method and apparatus for fast digital filtering that requires only filter stages of first and second order. A desired rational filter transfer function is represented as a sum of first and second order intermediate transfer functions. A time dependent input signal is first fed in parallel into a plurality of first and second order intermediate recursive filter stages. Then, the outputs of the intermediate filter stages are summed up to an output filter signal that corresponds to the desired rational filter transfer function. The method and apparatus reduces the amount of calculational effort to the order of O(N), where N denotes the number of sampling points in the time domain, because the digital filtering is based on a discrete recursive convolution in the time domain.

摘要： To estimate physical properties of a wired or wireless transmission channel it is proposed to sample a signal, received via the transmission channel, for example a system response of the corresponding transmission system, in order, on the basis of the sampled values thus obtained, to ascertain the moments of the order 0 . . . n of the received signal. Using these moments of the order 0 . . . n, n parameters of a transmission function of the transmission channel can be determined, wherein the parameters can be polynomial coefficients, zero points or coefficients of a residual notation of the transmission function. Using this transmission function the physical properties of the transmission channel, such as the attenuation and dispersion properties, can be determined exactly or at least approximately assessed.

摘要： Method for measuring and compensating skews of data transmission lines connecting at least one data transmission device with a data reception device via a parallel data bus comprising for each data transmission line the following steps: measuring the relative time delay of the data transmission line by transmitting a determined sequence of measurement vectors (MV) each consisting of an alternating bit pattern via said data transmission line, wherein the bit alternation frequency is halfed with every transmitted measurement vector (MV); comparing the received measurement vectors (MV′) transmitted via said data transmission line with corresponding reference vectors (RV) stored in said data reception device; shifting the received measurement vectors by inserting data unit intervals (UI) until a received measurement vector (MV′) matches a corresponding reference vector (RV); calculating a relative skew of the data transmission line depending of the number of inserted data unit intervals (UI) with respect to a slowest data transmission line; and compensating the calculated relative skew of the data transmission line by means of delay elements switched in response to the calculated relative skew.
