    Digital DC blocker filters
    (Berlin : De Gruyter, 2021) Tittelbach-Helmrich, Klaus
    This paper mathematically investigates a special kind of digital infinite-impulse response (IIR) filters, suitable for filtering out very low frequencies near zero from digital signals. We investigate the transfer functions of such filters from 1st to 3rd order and provide formulas to calculate the filter coefficients from the desired cutoff frequency.
