Signal processing apparatus for an ultrasound transducer, ultrasound receiver and method for operating an ultrasound receiver
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...

| Zusammenfassung: | 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. |
