Hello Veerendra, Some blocks, such as the Mux block, always generate virtual signals.  If you have an actual data available with you then you can generate similar kind of data and then signals from it. The Mux box can be integrated with the data written in text of .mfile to generate similar kind of virtual signals with the thresholds (of actual data) defined by user.

can i generate synthetic data for time history data(earthquake data) ? @ chandrakant Nirala

 Hello,

The easiest way is to calculate the Green's functions by some programs like Axitra (developed by Olivier Coutant, you can download it here: https://www.isterre.fr/annuaire/pages-web-du-personnel/olivier-coutant/article/logiciels-softwares). Then use the representation theory to calculate the accelerogram. you must convolve the Green's functions with your desired source-time function and multiply it by your moment tensor. Have a look at Quantitative Seismology by Aki and Richards for more information.

Cheers
