摘要：A method for the control of a phase shift between a transmission signal and areceived signal of an electromechanical transducer unit to a predetermined value in anoscillatory circuit. The received signal is sampled at discrete points in time predetermined

based on the transmission signal. Sampled voltage values are compared with desiredvalues, which the received signal assumes at the respective points in time, when thepredetermined phase shift is present, and, in the case of a deviation of a voltage valuefrom its desired value, based on the sign of the deviation, the frequency of thetransmission signal is decreased or increased.
