Computing device and signal enhancement method
A computing device provides a resonance algorithm to process digital signal data according to a principle of physical resonance. The resonance algorithm determines a division length n of digital signal data according to a frequency f1 of an audio signal to be detected and a sampling frequency f2, which is used for sampling the digital signal data by a coder. Furthermore, the resonance algorithm divides the digital signal data into a serial of data segments by the division length n, and obtains enhanced digital signal data by accumulating a number m of the data segments.
