Conceptually the circuit there is simple, consisting of the ultrasonic receiver, followed by a transistor amplifier for the modulated wave, then a diode for demodulation, another transistor ...

For the transmitter, the ultrasonic transducer is simply tied to one of the digital pins on the Arduino. The receiver is a bit more complex, requiring a LM386 amplifier and LM393 comparator to ...

This power-amplifier pair drives piezo and ultrasonic transducers for industrial and medical applications. The MP111 controls a pulsed 50-A output current on a 100-V single-ended supply and 500 ...

and an ultrasonic emitter or transducer powered by an ultrasonic amplifier. The signal processor converts the sound, such as music or a voice, to a complex ultrasonic signal. The transducer then ...

variable-gain amplifier, anti-aliasing filter, and 14-bit A/D converter with a 125 MSPS sample rate and 75 dB SNR performance. The AD9675 from Analog Devices is an 8-channel Ultrasound analog ...

is handled by the driver transistor to fire the ultrasonic sensor through the ultrasonic transformer, and the received/echo pulse is processed by a small signal amplifier (centered on the dual ...

The 20V digital input audio power amplifier offers 12.7mW of quiescent ... As well, the MAX98396 is ultrasound ready with 45kHz of bandwidth and a dedicated data path. This feature, combined ...
