| Abstract: | When an analog multiplier and a few elements are added to Moire Fringe interpolation circuit of the Single Chip Microcomputer system the error cause4 by the amplitude difference between the two pathes of the Moire Fringe signal is reduced distinctly. The resolution of this circuit is one time higher than that of the past. |
