Abstract
The spectral analysis of the signals generated by a physical system is a powerful way to analyse that system's behaviour. In the past the inability to achieve realtime analysis of signals and the high cost of spectrum analysers limited the use of this method of study in the area of physical system control. Today the availability of cheap and powerful devices - digital signal processors, overcomes the earlier problems. The paper presents a system for realtime spectral analysis based on a TMS32010 DSP chip. This system consists of two main components: a DSP board where data are processed, and a PC which acts as a terminal for the operator, as a display for the analysis results and as a temporary database. The system's hardware and software architectures and an application in seismic signal monitoring are describedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
