Abstract
Crosstalk between a drive coil and a feedback coil is eliminated by a motor drive circuit operative for generating the drive coil as a square wave, and by removing the crosstalk which occurs at zero transitions of a feedback signal. The drive coil is used to oscillate a scan mirror employed in an image projection arrangement or an electro-optical reader.
