摘要
介绍了运用NI设备PCI4461实现声学中的扫频测量、相位差测量等,用于测量声学原件的频响或相位,系统搭建更简捷,以替代传统声学仪器扫频仪和相位计等,在提高测试效率的同时,还可节省成本。
The way to measure the sweep frequency and the phase difference using PIC4461 is introduced, which can replace the routine acoustic instruments, including sweep generator and phase meter. This method can improve efficiency and reduce cost.
