A touch chip is to receive a first signal and a second signal from a stylus and includes a receiver circuit and a processor circuit. The receiver circuit is to receive the first signal and the second signal. The processor circuit is coupled to the receiver circuit and is to perform operations below: determining whether a signal intensity of the received first signal is greater than a first threshold value; determining whether a second signal is received when the signal intensity of the received first signal is greater than the first threshold value; determining whether a signal intensity ratio of the second signal to the first signal is greater than a second threshold value to generate a determination result when it is determined that the second signal is received; and performing an erase function according to the determination result.
