Abstract: The present technology relates to a signal processing device, a signal processing method, a program, and a measurement device which are capable of saving electric power while reducing a cost. The signal processing device mixes a periodical periodic signal with a reflection signal corresponding to reflection light reflected at a subject and filters, by a low pass filter (LPF), a mixed signal acquired by mixing the reflection signal with the periodic signal. The present technology is applicable to, for example, a measurement device that non-invasively measures a blood flow velocity under the skin by irradiating a human body with light and receiving reflection light reflected at the human body.

Abstract: In the work device that has a self-holding circuit (61) maintaining power supply from a power supply circuit (12) by output from a microcomputer (40) and has a structure in which stopping output to the self-holding circuit (61) causes interruption of power supply from the power supply circuit (12) to the microcomputer (40), the firmware of the microcomputer (40) is made to be rewritable and a power holding unit (condenser (C1)) for temporarily continuing power supply to the microcomputer (40) is provided, thereby realizing a so-called “off-delay timer function” for restarting the microcomputer (40). This configuration enables maintenance of power to the microcomputer (40) after update of the firmware even in a work device that cannot be restarted once power has been turned off unless trigger operation is performed, thereby enabling automatic restart of the microcomputer 40 after resetting is enabled.
