Abstract
PURPOSE: To obtain a detecting circuit of high sensitivity and good S/N by so setting circuit constant that the phase of the voltage appearing at the point of connection of a parallel resonance circuit of an inductance and a capacitor and resistors becoms near +30° or -30° with respect to a supply voltage.
