Claim Text:
1. A signal decomposition method, adapted to an electronic apparatus which has a processor, comprising: retrieving a first signal by the processor executing a retrieving module; performing a deterministic filtering operation to the first signal to decompose the first signal into at least one primary signal by the processor executing a first filter module, wherein the at least one primary signal comprises a second signal having a constant trend; and performing a non-deterministic filtering operation to the second signal to decompose the second signal into at least one secondary signal by the processor executing a second filter module, wherein one of the at least one secondary signal has the constant trend, and a sum of the at least one primary signal and the at least one secondary signal is the first signal, wherein the step that performs the deterministic filtering operation to decompose the first signal into the at least one primary signal comprises:
