Patent ID: 7917323

Claim:
A method of adjusting sensitivity of signal interpretation applied in a fan system, the method being executed by a processor and the method comprising the steps of: continuously receiving an input signal; setting a sampling parameter; sampling the input signal according to the sampling parameter to obtain a plurality of first sampling signals; calculating a first average of the first sampling signals; re-sampling the input signal according to the sampling parameter to obtain a plurality of second sampling signals; calculating a second average of the second sampling signals; and judging whether the first average and the second average are the same or not; generating a first control signal so as to be transmitted to a fan to update a rotating speed of a fan according to the sampling signals if the first average and the second average are the same; and generating a second control signal so as to let a fan hold an original rotating speed according to the input signal if the first average and the second average are not the same.
