摘要： A position transducer, and a noise elimination method for eliminating a noise component included in a received signal of the position transducer irrespective of the frequency band of the noise component. A position transducer calculates coordinates of a position indicator by effecting predetermined signal processing on the basis of a received signal developed in one of a plurality of loop coils, arranged side by side, as a result of electromagnetic interaction between the loop coil and the position indicator. The position transducer is further provided with a subtraction means which extracts an amplitude level corresponding to the signal developed in the loop coil only resulting from the electromagnetic interaction, for each loop coil, by subtracting a noise level obtained from a signal received when a transmission means interrupts transmission, from a signal received when the transmission means carries out transmission.
摘要翻译：位置传感器和噪声消除方法，用于消除包括在位置传感器的接收信号中的噪声分量，而与噪声分量的频带无关。位置传感器通过基于在环形线圈和位置指示器之间的电磁相互作用而并排布置的多个环形线圈中的一个中产生的接收信号进行预定的信号处理来计算位置指示器的坐标。位置传感器进一步具有一个减法装置，该减法装置从每个环形线圈的电磁相互作用中提取对应于在环形线圈中产生的信号的振幅电平，通过减去从传输装置从发送装置进行发送时接收到的信号中断发送。
