Abstract
In order to improve the detection accuracy of ultrasonic echo signals and ensure the useful signal could be absorbed, we study the Ultrasonic signal processing circuit. By comparing the limit, amplification, filtering and variable gain amplifier in order to choose the best option. The scheme we choose is through changing voltage to save all the low part to get more information, different from the option which gets rid of the large voltage directly.
