摘要： A method and system for the design and implementation of an optimally factored filter is presented. Pairs of angle values are organized in pairing candidates and a threshold is defined to indicate an upper bound on the number of pairing candidates. A first pairing candidate is exchanged above the threshold with a second pairing candidate below the threshold and a matrix is generated based on the pairing candidates below the threshold. A lowest predicted total quantization cost between all pairing candidates represented within the matrix is determined and the pairing candidates that result in the lowest predicted total quantization cost are used to determine the coefficients of the filter.

摘要： A method and system for the design and implementation of an optimally factored interpolated finite impulse response (IFIR) filter is presented. Techniques used to increase the implementation efficiency of the filter include joint sequencing of the filter stages, use of an nested IFIR filter, taming of a stage by relocation of that stage, fusing two or more stages together to form a single stage, and manual manipulation of a post-stage multiplier. IFIR filters using this approach may be realized as low pass filters or high pass filters, and in either analog or digital form.
