Rate (derivative) action is needed for steering a boat. The rate gain should be KD = 0.02%/(%/min). The error voltage range is -4.0 to +4.0 V, and the out-put signal varies from 0 to 2.5 V.
The fastest physical turning period is 0.4 min. Find the component values of a derivative-mode op amp circuit such as given Figure.
