| 摘 要： | 倒谱是频谱的再次分析，它对具有多成分边频的频谱图分析甚为有效。利用专作数字信号处理的DSP来实现倒谱计算，可设计出实时、高精度的倒谱分析系统。用C542DSK板实现原始数据采集和对数据进行倒谱运算，用TC3．0实现PC机与DSK板相互通信及计算结果的波形显示。本实验的研究结果可直接用于智能仪器的开发与制造。

| Abstract: | Inverse spectrum is the secondary analysis of the frequency spectrum, and it is applicable to multi ingredient margin frequency analysis. By applying DSP technique designed for digital signal processing to calculate inverse spectrum, one can get real time and high precision inverse spectrum analytic system. In t his paper, an integrated system is presented. This system employs C542 DSK board to collect data and to calculate inverse spectrum, and makes use of TC 3.0 to a ttain communication between PC and DSK board and results' demonstration. The ex perimental result can be directly used to design and produce intellectualized in struments. |
