摘要：The present disclosure discloses a method and a system for setting workingfrequency band of a touch detection system. A method for setting working frequency

band of a touch detection system includes the following steps of: collecting noisefrequency spectrogram in a touch detection system of a touch apparatus in a normaloperation mode; and, determining a frequency band which is within whole frequency bandsupported by the touch detection system and in which amplitude of the noise is less thana first threshold, according to the noise frequency spectrogram collected; and settingthe frequency band in which amplitude of the noise is less than the first threshold to beeffective working frequency band of the touch detection system. Meanwhile, the presentdisclosure also discloses a method and a system for suppressing noise in a touchdetection system.
