Abstract
An adaptive filter circuit using a time modulated dead band for suppressing the effects of spurious noise associated with an error signal used in controlling a position drive motor associated with process controlling elements. The circuit includes means for restricting all signals, including both control signals and spurious noise, to a positioning motor during those periods of operation when little positioning is required. However, in those instances where a relatively large amount of repositioning is required, the system provides means for switching to a nonrestrictive mode of filtering which thereby permits maximum control over motor operation.
