  • Method for measuring the modulation error of digitally modulated high frequency signals
    Patent number: 7453931
    Abstract: A method is described for measuring the modulation error in digital modulated high frequency signal, whose amplitude and/or phase is digitally distorted according to a predetermined function, in particular limited by a given clip factor, in which the signal to be measured is compared with a locally generated reference signal that was generated by taking the predetermined distortion function into account.
    Type: Grant

  • Method of determining parameters of an N-gate
    Patent number: 7158581
    Abstract: A method for determining the parameters and characteristics of an n-port network such as an amplifier is described. The parameters are determined by applying an input signal train or sequence with different amplitudes and measuring an output signal train, taking into account a temporal displacement that the output signal train has in relation to the input signal train. The temporal displacement is determined by a cross-correlation of the output signal train with the input signal train.

  • Method of determining parameters of an n-gate
    Publication number: 20020191711
    Abstract: The invention relates to a method for determining the parameters, in particular the characteristics of an n-gate, in particular in an amplifier (8). The parameters are determined by applying and optional simultaneous measurement of an input signal sequence with various amplitudes and measuring an output signal sequence, taking into account a skew which the output signal sequence has relative to the input signal sequence. The skew is thus determined by correlation of output signal sequence with the input signal sequence.
