How to apply Time synchronous averaging on a database

Good morning ; how to apply time synchronous veraging on a database not function . I have the vector ( vector : Acceleration=f(frequncy)) not a function. this database is imported from another software and I want to apply TSA on it Thank you so much. Greetings

TSA applies to signals, not functions or databases, so it's really not clear what it is you're asking.

Answer 1

I'm not sure what examples you're referring to. If you're talking about the examples in the tsa documentation, then none of the signals in these examples are functions.

You use

tsa(yoursignal, yoursamplingfrequency, yourpulsetime)

or

tsa(yoursignal, yoursampletime, yourpulsetime)

regardless of the original of yoursignal

Then you need to be a lot clearer about what you're asking. I have no idea what problem you're facing.
