SeismoSignal

Earthquake Software for Signal Processing of Strong-Motion data

Earthquake Software for Signal Processing of Strong-Motion data

SeismoSignal constitutes an easy and efficient way for signal processing of strong-motion data, featuring a user-friendly visual interface and being capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers.

The program is able to read accelerograms saved in different text file formats, which may then be filtered and baseline-corrected. Polynomials of up to the 3rd order may be employed for the latter, whilst three different digital filter types are available, all of which capable of carrying out, causal or acausal, highpass, lowpass, bandpass and bandstop filtering.

Due to its full integration with the Windows environment, SeismoSignal allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself.
