摘要
在电子工程、计算机、通信等领域中,正弦波信号是应用最多的电子信号。因而存在很多对正弦波信号进行测量的装置,传统的正弦波信号测量装置大多采用模拟电子技术进行设计,电路相对复杂并且在实际操作中存在很多不便之处。采用新型的32位高性能ARM Cortex-M3内核STM32作为控制器核心配以信号调理等电路,可实现对正弦波信号进行高速的测量,在液晶显示器上同步显示波形同时显示正弦波信号的幅度、频率、失真度等的参数并且采用触摸式操作具有良好的人机交互性。
The sine wave signals are the electronic signals most used in the fields of electronic engineering, computer science and communications. Thus there are many of the sine wave signal measurement device. The traditional sine wave signal measuring devices are designed by using analog electronic technology. The circuit is relatively complex and there are a lot of inconvenience in practice. Taking STM32 with new high-performance ARM 32-bit Cortex-M3 CPU core as the controller core, the device is equipped with the signal conditioning circuit to achieve high-speed measurement of the sine wave signal, and simultaneously display waveform and the parameters of ampitude, frequency, and distortion on the LCD monitor at the same time, which has a good human-computer interaction by means of a touch operation.
