置。This is a filter selection device that stops abnormal oscillation in an analog circuit, and includes an abnormal oscillation detector connected to the output side of the analog circuit to detect abnormal oscillation in the analog circuit, and a filter that sequentially switches based on the output of the abnormal oscillation detector. It is equipped with a switching element group that operates and a group of four filters connected to the switching element group, and an abnormal oscillation of the analog circuit is detected by an abnormality detector, and the switching element group is sequentially activated based on the detected output. A filter selection device that selects a filter that can be operated and then stopped from oscillating.
