Abstract
A circuit for use with a limited resolution device such as a stepper motor to convert a high-resolution signal such as from a computer into a high fidelity signal for driving the limited resolution device. The input to the limited resolution device being an average of the integrated difference between the high-resolution signal and a limited resolution signal consistent with the values used for driving the limited resolution device. This average being a high fidelity signal which is substantially the same as the high-resolution signal.
