摘要
在实验基础上提出了一种多通道正弦波信号发生器的设计模型,此信号发生器产生的信号频率和各通道相位差可根据实际需要进行调整,在信号测试等方面具有广泛用途,另外结合实例给出了系统各部分的硬件原理图、波形误差分析以及实验结果。
The design model of a multi-channel sine waveform generator is presented based on the experiment.The generated sign frequency and the phase difference between each channel can be tuned according the practical needs,and it is useful in the application of sign measurement process.Finally,the hardware principal figure is given,the waveform error is analyzed,and the results of the experiment indicate that it is a effective method in the process of sign measurement.
