<p><P>PROBLEM TO BE SOLVED: To provide a signal processing unit which keeps power consumption low by reducing signal throughput and which removes a noise component from a time-series signal. <P>SOLUTION: The signal processing unit generates one reference signal on the basis of a first time-series signal including a first signal component with periodicity and a first noise component, a second time-series signal including a second signal component having a predetermined relationship with the first signal component and a second noise component having a predetermined relationship with the first noise component, and a predetermined relationship between the first and second noise components, generates a plurality of other signals, in which the predetermined relationship between the first and second noise components is changed by each predetermined difference, according to a recurrence formula by using data calculated from the first time-series signal and the predetermined difference, and estimates the predetermined relationship between the first and second noise components in a first predetermined time range by using the periodicity of the generated signal in the first predetermined time range. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
