Abstract
A waveform correction apparatus is disclosed. The waveform correction apparatus includes a signal generator for generating a signal; a maximal value recorder for recording a maximal value of the signal waveform; a minimal value recorder for recording a minimal value of the signal waveform; a difference value generator for generating a difference value of the maximal value and the minimal value; and a comparative controller for comparing the difference value with a reference value. The comparative controller outputs a corrected waveform when the difference value is larger than the reference value, otherwise it outputs the original waveform generated by the waveform generator. The corrected waveform is formed by shifting up or down the original waveform by a constant value.
