Abstract
In this invention an all electronic circuit for moving and stopping an object is disclosed. The object is responsive to movement from a drive signal. The object is moved from a first position to a final position and is stopped without physical damping or substantial ringing and the like. The circuit provides for the generation of a first signal which moves the object from the first position to an intermediate position, which is between the first position and the final position. A second signal is generated where the second signal is a time delay signal of the first signal. The first and second signals are combined to produce the drive signal.
