<p>A stairstep output waveform representative of a wave form measured e.g. by an electro-optic voltage measuring system is generated in a digital computer from a bidirectional cumulative count of zero crossings of two electric signals generated by the voltage measuring system which count is incremented or decremented depending upon which of the two electrical signals is leading. Improved accuracy of the output signal is achieved by adjusting the stairstep waveform by the magnitude of the smaller of the two electrical signals, with the sense of the adjustment determined by the relative polarities of the two electrical signals. <IMAGE></p> |
