    • A sampling rate conversion apparatus and a method thereof are provided which increase the sampling rate of a discrete audio signal sampled at a predetermined sampling rate by using a fractal interpolation function (FIF). An audio signal portion formed by a predetermined number of sampling data items is divided into a plurality of interpolation intervals. On the audio signal portion, mapping points are determined. The number of the mapping points is in accordance with the degree of increase in the sampling rate. For the respective interpolation intervals, mapping parameters for performing mapping using the FIF on the mapping points are calculated. In all of the interpolation intervals, the mapping using the FIF is performed on the mapping points with the use of the mapping parameters according to the respective interpolation intervals. Thereby, new sampling data items are generated.

    • A capacitance detecting circuit includes a code generator for generating code having orthogonality in chronological order. A column-line driver drives the plurality of column lines based on the code by dividing the column lines into a first column line group and a second column line group. A capacitance detector, which is connected to the row line, converts the total of currents generated in capacitances at the intersections with the driven column lines into a voltage signal and outputs the converted voltage signal. A decoding computation unit determines the voltages corresponding to the capacitances at the intersections for each of the column line groups by performing product sum computation between the measured voltages and the code. The column-line driver drives the first column line group and the second column line group by complementary voltages according to the code or information indicating the inversion of the code.
