Abstract
PURPOSE:To make the frequency band broad, by applying the input fed to a detecting circuit for the 1st peak value also to a detection circuit for the 2nd peak value via a frequency selection circuit consisting of an inductance and a two-terminal type piezoelectric resonator. CONSTITUTION:One end of a resonator 6 is connected to each one end of a resistor 5 and a capacitor 7 via a coil 9. Further, by making the inductance of the coil 9 as a required value, the peak point of S-shaped characteristic curve is shifted to lower band. Thus, by setting the resistance value of the resistor 5 and the inductance of the coil 9, the S-shape characteristic curve can be changed finely.
