SIGNAL GENERATING CIRCUIT, RELATED CHIP, FLOW METER, AND METHOD

摘要

Disclosed is a signal generating circuit (100), which is used for generating an emission signal to trigger a first transducer to generate a first transducer output signal. The signal generating circuit comprises: a signal generating unit (106) for generating a transmission signal; and an emitter (104), which is coupled to the signal generating unit and used for converting the transmission signal into the emission signal, wherein the emission signal comprises a data signal and a compensation signal. The data signal at least comprises a first pulse wave, and the compensation signal at least comprises a second pulse wave. The phases of the first pulse wave and the second pulse wave are opposite, and the first pulse wave and the second pulse wave have other different waveform parameters. The present application further provides a related chip, a flow meter, and a method.
