Applicant: Enrico Dolazza For: Digital Signal Filter Circuit ABSTRACT OF DISCLOSURE A digital signal filter circuit for convolving a sequence of data samples with a kernel of n coefficients where the coefficients have as an envelope a polynomial function of degree q, including: first means for extracting a first set of q+1 contiguous data samples; means for storing n-(q-1) intermediate data samples following the set of (q+1) contiguous data samples; second means for extracting from the sequence of data samples a second set of (q+1) contiguous data samples that follow the intermediate data samples; means for linearly combining the data samples of the first and second sets with weighting values that are a function of the coefficients of the polynomials to obtain a linear combination of (q+2) sequential convolved samples with binomial coefficients; and means for recursively selecting one of the convolved samples from the linear combination of (q+2) sequential convolved samples.
