摘要:: 高声压二值逻辑电路是一种特殊类型的电路。为了处理来自高声压环境下的声信号，并能够对这些信号进行快速准确的逻辑处理，该文设计了一种成本较低、结构简单的处理声信号的二值逻辑电路系统，其输出为二值逻辑信号，处理时具有数据量小以及便于快速传输的特点，可以很好地满足对声信号实时处理的要求。系统设计时，根据传感器选择类型设计电路的各个模块，对信号进行放大和滤波处理，通过传感器对不同声压下的声信号的接收能力设置不同的电压阈值，根据不同阈值的触发状态可以快速地对声信号进行处理。此外，还通过模拟测试验证了设计的可行性。

Abstract:: High sound pressure binary logic circuit is a special type of circuit. In order to process sound signals from high sound pressure environment, and to process these signals quickly and accurately, this paper designs a binary logic circuit system with low cost and simple structure. Its output is binary logic signal, and it has the characteristics of small data amount and easy to transmit quickly, which can well meet the requirements of real-time processing of sound signals. During the system design, each module of the circuit is designed according to the type of sensor selection, and the signal is amplified and filtered. Different voltage thresholds are set through the sensor for the receiving ability of the acoustic signal under different sound pressure, and the acoustic signal can be processed quickly according to the trigger state of different thresholds. In addition, the feasibility of the design is verified by simulation tests.
