The Interesting Effect of Non-uniform Sampling

Adam Derkowski
  • Abstract:
    It is well known, that the proper ratio between frequencies of testing signal and sampling signal is required, during a dynamic testing of waveform recorders or analog-to-digital converters. A lot of testing methods suggest applying a coherent sampling, which assures a uniform distribution of samples between 0 and 2π. The paper presents results obtained with Matlab numerical simulations showing influence of the sampling strategy on establishing performances of analog-to-digital converters. It was shown, that the results of tested conversions are different if a non-coherent sampling is applied. A proposal of sampling is presented in case of using a sinewave as an exciting, input signal.
