【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.更多还原
