NON-RECURSIVE DIGITAL FILTER

A non-recursive digital filter has N predetermined filter coefficients to perform a specific computation in response to a sequence of consecutive binary codewords. The absolute values of the computation coefficients are arranged in an order of magnitude. The filter arranges the sequence to obtain a sequence corresponding to the arranged coefficients. A product is obtained for each sequence, which is given by the arrangement and by the corresponding polarity of each of the coefficients. The outputs given by these products are accumulated and are multiplied by certain differences.
