Abstract:
A carrier signal detection apparatus, a touch control apparatus and detection methods thereof are provided. The carrier signal detection apparatus includes an analog to digital converting (ADC) apparatus and a filter. The ADC apparatus receives an analog input signal and converts the analog input signal to a digital signal. The filter receives the digital signal and accumulates the digital signal according to a delay time for generating a carrier signal detection result.
