Abstract
A signal processing device (100) includes a prediction circuit (20) configured to generate Vb_T2 corresponding to an output signal to be obtained at T2 after T1, in accordance with Va_T1 obtained at the time T1, in a transition response period before Tr or Td elapses, where Tr denotes a time period during which an output signal Va(T) of a sensor (80) changes from a converged value Vc1 corresponding to a parameter P1 representing a certain property of an object to be measured to a converged value Vc2 corresponding to P2, and Td denotes a time period during which Va(T) changes from Vc2 to Vc1. The prediction circuit generates the predicted value so that TrE<Tr, TdE<Td, |1−Td/Tr|>|1 −TdE/TrE| are satisfied, where TrE denotes a time period during which the predicted value becomes a value corresponding to Vc2, and TdE denotes a time period during which the predicted value becomes a value corresponding to Vc1.
