  • Method and apparatus for determining the value of a sample in the mth position of an ordered list of a plurality of samples
    Patent number: 4933978
    Abstract: A method and apparatus for determining the value of a sample having a particular position in an ordered ranking, by magnitude, of a set of digital samples includes means for truncating the lesser significant bits of the samples. Further means compares the values of the truncated samples and generates selection control signals indicating the truncated sample which is in the desired position of an ordered ranking of the truncated samples. A function generator then generates a function of the samples, corresponding to the selected truncated samples.

  • Adaptive median filter system
    Patent number: 4682230
    Abstract: An adaptive median filter system is disclosed. Circuitry is arranged to produce successive sets of samples from an input signal which may possibly include noise. An adaptive median filter filters the samples in response to a control signal. Further circuitry estimates the relative density of the noise in the input signal to generate the control signal supplied to the adaptive median filter.
