,基于LabVIEW这个软件开发平台。虚拟函数发生器的设计参考了常见信号发生器的功能,在功能上有所扩展。仪器主要功能如下: 1可产生实验室常用的正弦波、方波、三角波、锯齿波。2任意波形的发生,任意波可实现公式输入。3信号频率、幅度、相位、偏移量、方波占空比可调可控-Based on LabVIEW software development platform. The design of the virtual function generator reference to the common signal generator, the function has been expanded. The main function of the instrument as follows: 1 can produce a commonly used laboratory sine wave, square wave, triangle wave, sawtooth wave. 2 Arbitrary Waveform occurrence of any wave can be achieved formula. 3 signal frequency, amplitude, phase, offset, square wave duty cycle adjustable and controllable
