基于LabVIEW和MyDAQ的虚拟信号处理仪器设计

随着计算机软、硬件的不断更新,计算机与外界的信息交流日趋频繁.在这些信息交换广泛运用和发展的基础上,美国国家仪器公司提出了虚拟仪器的概念,强调软件即仪器的观点.本文基于LabVIEW平台,利用myDAQ完成函数发生器、示波器等虚拟仪器的设计.仿真结果表明,本文设计的虚拟仪器具有较好的信号产生、信号仿真及采集功能.

Virtual Signal Processing Instrument Design based on LabVIEW and MyDAQ

With the update of computer hardware and software, computer communication with the outside world has become increasingly frequent. Because of the information exchange and development, National Instruments puts forward the concept of virtual instrument, emphasized"The soft is the instrument".Based on the LabVIEW platform,we use the MyDAQ to complete the design of virtual function generator and oscilloscope, etc. The simulation results show that the design of virtual instrument has good signal and the signal and acquisition function.
