SIGNAL PROCESSING DEVICE |
摘要 |
A signal processing device includes: a signal processing circuit that processes an input signal, and outputs a signal corresponding to the input signal; an offset input device that inputs a diagnosis offset signal as an internal signal in a passage between an input side and an output side of the signal processing circuit; a self-diagnosis device that performs a self-diagnosis of the signal processing circuit based on a variation in the signal output from the signal processing circuit when the diagnosis offset signal input by the offset input device is varied by a predetermined amount; and an extraction device that removes a component of the diagnosis offset signal from the signal output from the signal processing circuit, and extracts only a signal corresponding to the input signal. |

1. A signal processing device comprising:
a signal processing circuit that processes an input signal, and outputs a signal corresponding to the input signal; an offset input device that inputs a diagnosis offset signal as an internal signal in a passage between an input side and an output side of the signal processing circuit; a self-diagnosis device that performs a self-diagnosis of the signal processing circuit based on a variation in the signal output from the signal processing circuit when the diagnosis offset signal input by the offset input device is varied by a predetermined amount; and an extraction device that removes a component of the diagnosis offset signal from the signal output from the signal processing circuit, and extracts only a signal corresponding to the input signal. |
