Abstract
[Object] To allow a pen to properly receive an uplink signal even if there is dullness in a waveform of the uplink signal. [Solution] Provided is an invention of a method of transmitting transmission data from a sensor controllerthat detects a pento a pen through a sensor electrode group. The penincludes a pen tip electrode arranged near a pen tip, an analog circuit that detects edges of a signal led to the pen tip electrode, and a digital circuit that performs a correlation operation of an output signal of the analog circuit and known patterns to detect transmission data. The sensor controllergenerates a pulse signal representing the transmission data and transmits the pulse signal, by using a main signal and a sub signal of the pulse signal so as to enhance the edges, thereby transmitting the transmission data through the sensor electrode group.
