Abstract
The present disclosure discloses a method and a system for setting working frequency band of a touch detection system. A method for setting working frequency band of a touch detection system includes the following steps of: collecting noise frequency spectrogram in a touch detection system of a touch apparatus in a normal operation mode; and, determining a frequency band which is within whole frequency band supported by the touch detection system and in which amplitude of the noise is less than a first threshold, according to the noise frequency spectrogram collected; and setting the frequency band in which amplitude of the noise is less than the first threshold to be effective working frequency band of the touch detection system. Meanwhile, the present disclosure also discloses a method and a system for suppressing noise in a touch detection system.
