Abstract

Signal processing apparatus includes: an input interface configured to receive an output signal V_a(T) from a sensor; a prediction circuit configured to generate, on the basis of a relationship different depending on each of a plurality of converged values V_c, a plurality of predicted values V_{b_T2} corresponding to a value of the output signal that would be obtained at a time T2 after a time T1, in a transition response period before a response time period Tr elapses where Tr denotes a response time period required for a value of the output signal V_a(T) to become a converged value V_c corresponding to a value P of a parameter representing a certain property of an object to be measured, in accordance with a value V_{a_T1} of the output signal obtained at the time T1; and an estimation circuit configured to generate, on the basis of the value V_{a_T2} of the output signal obtained at the time T2 and the plurality of predicted values V_{b_T2}, an estimated value Pe of a parameter representing the certain property of the object to be measured.
