“多通道实时FFT信号分析仪”是四机部仪器处下达的研制开发的新任务,为此,在确定方案之前,前后花了达四个月的调查了解,这部分是国内情况,是设计方案的依据之一,也是使用数字信号处理机关心的情况。 “Multi-Channel Real-Time FFT Signal Analyzer” is a new task developed and issued by the four-machine department instrument department. For this reason, it took four months to investigate before and after determining the solution. This part is the domestic situation and is designed One of the rationales for the program is also the case for using digital signal processors.
