Abstract
A method and apparatus of processing waveforms acquired in a waveform digitizing instrument utilizing multiple, interleaved digitizing elements is provided to improve the accuracy of the data acquired is provided. The present method utilizes measured analog-to-digital converter frequency response characteristics to generate sets of coefficients. When data is acquired by a waveform digitizing system, the present method utilizes these coefficients to correct the waveform, thus undoing the adverse effects of the non-ideal frequency response characteristics, resulting in a waveform acquired with higher fidelity. The waveform resulting from this method is a waveform that more closely represents the signal sampled by the digitizing system.
