Abstract
Low-frequency equalization of a digitized electrocardiographic waveform has been accomplished by adding to the waveform several of its integrals, appropriately weighted. The weighting factors required for correction of distortion produced by a particular amplifier are initially obtained from a least squares correction of its step response. Neither analysis of the amplifier circuit, nor frequency-response testing is necessary.Keywords
