Abstract
A signal processing apparatus for a tool including a rotating body rotated by impacts delivered from a drive apparatus is provided with: a filter a calculation circuit and a control circuit. The filter receives a torque value signal indicating a torque applied to the rotating body, and filters the torque value signal. The calculation circuit sets a filter coefficient of the filter based on a number of impacts delivered to the rotating body. The control circuit controls the impacts delivered to the rotating body, based on the torque value signal filtered by the filter.
