  • Signal processing apparatus for an ultrasound transducer, ultrasound receiver and method for operating an ultrasound receiver
    Patent number: 7586813
    Abstract: To reduce signal interference and improve the signal-to-noise ratio in the transmitted signal, the analog signals produced by an ultrasound transducer are promptly digitized. In accordance with the invention, the demodulator is already shielded from the ultrasound transducers, immediately after the preamplifier, which is itself shielded from the ultrasound transducers, by an analog to digital converter, for example.
