  • Patent number: 5893899
    Abstract: A method and apparatus for sampling an analog signal permits the identification of those samples in which data was lost in the sampling process. A data reference element is generated for each sample element, the data reference element having a corresponding sample element. A user friendly display technique is provided to permit the user to controllably display the sampled signal, clearly showing those portions of the signal in which information was lost contrasted with those portions of the signal that were sampled intact.
    Type: Grant
    Filed: February 24, 1997

  • Patent number: 5543792
    Abstract: A sampler develops a digital representation of an analog signal at a predetermined sampling rate. The highest frequency of a period of samples is determined and, if sampling rate of the sampler exceeds the Nyquist rate, indicating oversampling, redundant sample points are discarded from the period and the reduced record is stored. A multiplicity of periods make up a recorded session. To reconstruct the original signal, a common time domain is determined and the reduced records are expanded based upon the common time domain.
