摘要
利用倒频谱特点来检测信号功率谱中的周期信号,有利于监测者进一步分解和识别故障频率。为此,介绍了使用以TMS320C55x系列芯片为基础的DSPLIB库函数实现倒频谱运算的方法。以某大型空压机增速箱输出端采集数据为例,证明该算法不仅可以提高信号处理的速度与可靠性,还可以大大加快开发速度。
Using cepsturm characteristics to test signal power spetrum for periodic signal is benefical to further analyse and recog- nize fault frenquency. Cepstrum algorithm was achieved in fixed DSP TMS320C55x. Using DSP library on TMS320C55x DSP, the speed and the reliability of the signal processing were improved and the developing speed was quickened. The realization of the cepstrum algorithm was studied using DSP library.
