    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: A device for setting a clock delay is proposed, wherein delayed output clock signals are generated with the aid of delaying means by delaying an input clock signal. The delaying means are configured to provide several differently delayed clock signals simultaneously. The device is configured to generate the at least one output clock signal depending on the differently delayed clock signals with a settable phase relationship to the non-delayed input clock signal, wherein the phase relationship is settable independently of the delay provided by the delaying means. It is particularly provided that the phase relationship between the delayed output clock signal and the non-delayed input clock signal is automatically controlled to a desired phase relationship independently of the delay supplied by the delaying means.

    摘要: The present invention relates to a method and apparatus for generating an output signal in dependence on a phase difference between two periodic signals. The present invention is particularly useful in phase locked loops and delay locked loops, in which a controllable oscillator or a controllable delay device is controlled on the basis of the phase difference determined by means of phase detection, in such a way that a control signal can be obtained, the phase lag or frequency of which has a firm relationship to the reference signal.
