  • Method of high pass filtering a data set
    Patent number: 6790688
    Abstract: An improved method of high pass filtering a data set includes flattening the data set and then filtering the flattened data set with an adaptive filter. The data set is flattened by fitting it to a predetermined function, and then obtaining the difference between the original data set and the fitted data set. Beneficially, the predetermined function is a polynomial. The adaptive filter includes a masking function that has a constant, non-zero value (e.g., 1) within the bounds of the original data set and value of zero outside the bounds of the original data set.
