摘要
本文介绍了一种以高速DSP数字信号处理器为基础的冲击振动测试系统。系统中分裂基、旋转矢量FFT的递归算法的应用实现了对冲击振动信号的快速频谱分析。该系统具有高速实时测试能力。
An integrative shock and vibration measurement system based on high -speed DSP processor is introduced. Fast speed frequency analysis of shock and vibration signal is realized by application of FFT recursion algorithm based on split - radix and twiddle vector. High speed and real - time measurement power is achieved in this system.
