Abstract
PURPOSE:To enable to form HPF easily, by producing the charge corresponding to the signal amount at LPF having inverse characteristics as desired HPF, in opposite phase. CONSTITUTION:The charge group as the first sample remains at the area surrounded with the area 21 and the electrode 26 and a part of the charge group of the second sample remains at the area surrounded with the area 21 and the area 28 at the next period. In the succeeding period, the charge group as the third sample value remains at the area surrounded with the areas 21 and 28. When the pulse fed to the electrode is of high potential, the charge group of the third sample value moves under the area 28 and it is mixed and summed to the sum of the first and second sample values. Thus, by producing the charge corresponding to the signal amount at LPF having inverse characteristics as desired HPF in opposite phase, HPF can easily be formed.
