| Zusammenfassung: | A signal processing system (10) includes a switching circuits (6) which switches between subsystems (5a, 5b), on a basis of a frequency of noise mixed in each of time-series signals, the amount of that noise, and input-output transfer characteristics, to reduce noise present in a result of estimation of the value of a linear element (CX), which estimation is performed by addition- and subtraction-based signal processing. |
