Abstract :
A novel approach to designing recursive stable digital differentiators is introduced. A four-step design procedure is presented. The procedure consists of obtaining or designing an integrator and then modifying its transfer function appropriately to obtain a stable differentiator. As an example a second order recursive differentiator is developed.
