Abstract: The invention relates to both a method and an apparatus for separating data and clock signals from a self-clocking encoded input signal by means of a self-clocking detector system which employs clock circuitry operating at the same frequency as the data rate embodied in the self-clocking encoded input signal.

Abstract: SAMPLE DATA POSITIONING SYSTEM EMPLOYING A MODEL OF THE PHYSICAL SYSTEM FOR TIME OPTICAL CONTROL A sampled data positioning system for moving a member between positions in a minimum time employs a model of the physical system to overcome the low bandwidth constraints of fed back position and velocity samples. The model system is an approximate analog of the physical system and provides continuous pseudo position and velocity signals of high bandwidth. These are applied to a seek controller which generates an error signal between a desired reference velocity trajectory and the pseudo velocity signal. The error signal is fed back to the model system input and is also applied to control the physical system. The model velocity and position outputs are reset at sampling times to the values of the sampled velocity and position in the physical system.
