Abstract
A filter circuit includes a processor configured to compare a current input value with a last-time output value, add a first correction value to the current input value and to the last-time output value if a comparison result between the current input value and the last-time output value is greater than a predetermined value, and add a second correction value smaller than the first correction value to the current input value and to the last-time output value if the comparison result is smaller than or equal to the predetermined value, and calculate a current output value based on the current input value and the last-time output value to each of which the first correction value or the second correction value has been added.
