Abstract

PURPOSE:To simplify a resonance circuit and to save power and to make the distortion factor low, by constituting the resonance circuit which can selectively obtain a number of resonance frequencies with one amplifier. CONSTITUTION:When the K-th input terminal AK is alternatively selected, the J-th input capacitor BJ and the (J-1)th input resistor FJ-1 inserted between a connecting point EJ-1 other than a connecting point EK-1 and the J-th input terminal AJ other than the K-th input terminal AK are niglected, and the synthesized resistance value of the 1st - the (K-1)th voltage dividing resistors D1-DK-1 inserted in series between the connecting point EK-1 and the input terminal of an amplifier 21 can be neglected because the input impedance of the amplifier 21 is close to infinite value. Thus, this resonance circuit becomes equivalent to the series connection of a capacitor in CK, resistor which is the sum of RK-RN+1 and HK-1 and inductance in value of [(sum of RK-RN)XRN+1XC0].
