Frequency synthesis of digital filters based on repeatedly applied unweighed moving average operations.
Simple formulae are presented for designing filters based on repeatedly applied moving average operations with unit coefficients. Design formulae are derived to synthesise the filter in a way that satisfies specified passband and stopband specifications. These filters are attractive because of the reasonable frequency characteristics, the computational efficiency of the design and filter algorithms, and the uncomplicated implementation in software.
