Abstract

PURPOSE: To detect the rotary information stably with an excellent S/N ratio by connecting an inductance with a condenser, which has its capacitance varying with the rotations, to form a resonant circuit so as to detect the amplitude modulating signals corresponding to capacitance variation.
