Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND SIGNAL PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/286507
Kind Code:
A1
Abstract:
This signal processing device (1) has: a first signal acquisition unit (51) and a second signal acquisition unit (52) for acquiring a first signal (D11) and a second signal (D12), which are time series data; a first signal processing unit (53) and a second signal processing unit (54) for acquiring a first processed signal (D21) and a second processed signal (D22) from the first signal (D11) and the second signal (D12); and a difference processing unit for acquiring a separation signal (D3) that is the difference between the first processed signal (D21) and the second processed signal (D22). The first signal processing unit (53) and the second signal processing unit (54) perform at least standardization processing on the first signal (D11) and the second signal (D12), thereby making it possible to properly match the scales of the first signal (D11) and the second signal (D12). Thus, when the second signal (D12) is a signal is a signal in which a signal proportional to the first signal (D11) and a signal weaker than the aforementioned signal are superposed, the weak signal component can be properly extracted.
