    Abstract: An electronic apparatus includes a sensor system, an excitation generating unit which generates an intermittent sine wave signal and applies the same to the sensor system, and a demodulation unit which demodulates an amplitude modulated signal which is an output of the sensor system, in which the demodulation unit generates a demodulated signal using both a response of the sensor system in a period when the excitation generating unit outputs a sine wave and a response of the sensor system in a period, at least either immediately before or immediately after the above-mentioned period, when the excitation generating unit does not output a sine wave.

    Abstract: When an excitation frequency of a touch panel is coincident with or in the vicinity of a frequency of external noise, noise cannot be removed by a bandpass filter. Also when a touch detecting operation period is limited to a short period of time such as a non-address period, frequency resolution is reduced and a noise removal effect of averaging is reduced, so that an S/N ratio is decreased. The electronic apparatus of the present invention includes a sensor system 101, an excitation generating unit 102 which generates an intermittent sine wave signal and applies the same to the sensor system, and a demodulation unit 105 which demodulates an amplitude modulated signal which is an output of the sensor system, in which the demodulation unit generates a demodulated signal D(t) using both a response x1(t) of the sensor system in a period when the excitation generating unit outputs a sine wave and a response z1(t) of the sensor system in a period, at least either immediately before or immediately after the above-mentioned period, when the excitation generating unit does not output a sine wave.

    Abstract: X and Y electrodes arranged on a support substrate of the tactile sense presentation device are divided into M groups (here, M≥2, M=4 in FIG. 14). When a presentation content of a tactile sense transits from the N-th frame to the (N+1)-th frame, the device, first, sets electrodes belonging to a group 1 to a floating state for a predetermined time and then, connects each electrode to an AC voltage signal source or the ground so as to present a tactile sense in the (N+1)-th frame. The device sequentially performs this operation for each group, and, when the operation of group M ends, transition between frames ends, and movement of the target area in which a texture sense is presented is completed. There is no case where all the electrodes are in the floating state together, and there is no interruption of the texture sense.
