Abstract
PURPOSE: To obtain a signal which is modulated by a signal frequency of equivalently large cycle, by switching alternately the two different frequency signals with a signalof a large cycle frequency. As a result, a sontrol signal of an accurate phase can be reproduced without receiving any effect due to a magnetic distortion, etc.
