In the last century, researchers and scholars focused on studying dynamic effects on buildings and machines. This big effort led to a wide variety of analysis methods, that can be collected in two big categories: Operational and Experimental Modal Analysis. Nowadays a lot of commercial softwares are equipped with several different methods in order to give the best results in every situation and the trend tends to the development of routines that are always more automatic in order to be simple and quick to use. In this work a fully automatic EMA method will be developed and tested with both numerical and real systems.
