An approach to the detection of the starting time of an earthquake that operates in the frequency domain is presented. It is based on the use of a digital signal processor chip. The key is the device's ability to perform both a real-time spectrum analysis of the signal and a fast computation of a suitable function able to highlight the starting of the earthquake. The validity of the approach is established through several examples and a comparison with other tools that work in the time domain.

Abstract
An approach to the detection of the starting time of an earthquake that operates in the frequency domain is presented. It is based on the use of a digital signal processor chip. The key is the device's ability to perform both a real-time spectrum analysis of the signal and a fast computation of a suitable function able to highlight the starting of the earthquake. The validity of the approach is established through several examples and a comparison with other tools that work in the time domain.File in questo prodotto:
