    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 translation: 当触摸屏的激励频率与外部噪声的频率一致或附近时，带通滤波器不能消除噪声。 此外，当触摸检测操作周期被限制在诸如非寻址周期的短时间段时，频率分辨率降低，并且平均化的噪声去除效果降低，使得S / N比降低。 本发明的电子设备包括传感器系统101，产生间歇正弦波信号并将其应用于传感器系统的激励产生单元102，以及解调单元105，其解调作为输出的振幅调制信号 传感器系统，其中解调单元在激励产生单元输出正弦波的周期和响应z1（t）的两个周期内使用传感器系统的响应x1（t）产生解调信号D（t） 传感器系统在至少在上述期间之前或之后的时间段内，当激励发生单元不输出正弦波时。
