Abstract:
This signal processing system (10) has a switching circuit (6) which, on the basis of the noise frequency mixed in with a time-series signal, noise amount and input-output transfer characteristics, switches between subsystems (5a, 5b) in order to reduce noise present in the result of performing addition- and subtraction-based signal processing for estimating the value of a linear element (CX).
