Abstract

A DSP-based FFT analyzer, capable of adapting its behavior on the basis of the specific application requirements was set up. A suitably designed user-interface allows the specific application to be chosen and its main parameters to be defined. Then an automatic optimization procedure organizes both the hardware and with the aim of satisfying the user requirements. The implementation on a multi-DSP architecture allows a real-time behavior to be assured. The experimental tests carried out highlight the instrument capability to optimally operate in a large number of typical applications
