Abstract
The signal processing system (1) includes an A / D conversion device (100) and a setting device (20). The A / D conversion device (100) includes an A / D conversion unit (102) that converts an analog signal into a digital signal, and a digital filter unit (105) that filters the digital signal. The setting device (20) includes a reduction component identification unit that identifies frequency components to be reduced based on a user's designation, a characteristic determination unit that determines filter characteristics for reducing the frequency components identified by the reduction component identification unit, and a setting unit that sets the filter characteristics identified by the characteristic determination unit in the digital filter unit (105) of the A / D conversion device (100). The digital filter unit (105) filters the digital signal based on the filter characteristics set by the setting unit of the setting device (20).
