Abstract: A noise frequency detection method includes steps of: providing a frequency of system clock; fixing an operation frequency band of a sensing signal; adjusting a pulse width of the sensing signal and sampling a noise, wherein each pulse width of the sensing signal corresponds to a noise value of the noise; and referring the pulse width corresponding to a preset value of the noise to as a critical value, and obtaining a noise frequency from dividing the frequency of system clock by the critical value. A touch apparatus is also provided.
