摘要
介绍了利用ICL8038芯片制作的一种模拟信号源的设计方法,该信号源具有输出三角波、正弦波和方波等多个波形并且输出电压和频率可调的特点,可模拟飞行器发动机开车时发电机和永磁机产生的交流电,实现了飞行器在地面无需发动机开车即可对电子设备实施自检测的目的。
A designing method of using the ICL8038 chip to manufacture one simulation signal source is introduced. This signal source has some characteristics ： the triangular wave, the sine wave and the square - wave and so on many waves,and the output voltage can he output from the signal source;the frequency can be adjusted. The AC which from the dynamo and permanent magnetism machine when the flight vehicle＇s engine functioning can be simulated. So the purpose to examine the electronic installation by oneself is realized when the flight vehicle functioning no engine in the ground.
