摘要
A circuit is provided for supplying a transmission oscillator voltage suitable for a piezoelectric sound source transducer in which the transducer also serves as a receiving transducer. The circuit contains an electrical series resonant circuit having a capacitor C and an inductor L with LxC=(1/2 pi f0)2, wherein the electrical series resonant circuit is matched to the series resonant frequency f0 of the transducer and is connected parallel to the transducer. The circuit further contains a pair of diodes, connected anti-parallel to one another, and connected in parallel to either the inductor L or to the capacitor C, with the output of the receiver being connected to the capacitor C or to the inductor L.
