A multi-application FFT analyzer based on a DSP architecture

A digital signal processor (DSP)-based FFT analyzer capable of adapting its behavior according to specific application requirements was set up. A suit ably designed user-interface allows both the specific application to be cho sen and its main parameters to be defined. An automatic optimization proced ure then reorganizes the instrument configuration in order to meet user req uirements. Multi-DSP architecture implementation ensures real-time behavior . The experimental test results indicate that the instrument is capable of optimally operating in a large number of typical applications.
