Abstract
A signal transmitting method includes: performing amplitude modulation respectively on n binary codes that represent information to be transmitted so as to obtain n coded amplitude modulation signals sequentially arranged, wherein n is an integer greater than 1; and continuously transmitting the n coded amplitude modulation signals which are sequentially arranged. The coded amplitude modulation signals, sequence numbers of which are odd, are transmitted at a preset first frequency, and the coded amplitude modulation signals, sequence numbers of which are even, are transmitted at a preset second frequency, whereby fault-tolerant time between coded amplitude modulation signals is saved, transmission time of the same number of coded amplitude modulation signals is reduced, and time required by a screen for completing detection on the coded amplitude modulation signals is reduced, thereby promoting a report rate and improving the anti-interference ability of the screen.
