Abstract :
The paper deals with a signal analyzer for real time detection and analysis of transients. In particular, the analyzer implements a suitable procedure, based on the wavelet transform, for analyzing disturbances affecting the power supply voltage. It mounts a good performance digital signal processor and adopts the VXI standard interface. Hardware and software solutions are described in detail. Experimental results on signals characterized by different disturbances with known characteristics assess the reliability of the proposed analyzer
