I am pretty new in the field of Signal Processing. I am a structural engineering graduate student at the UT at Austin. I am currently working on a project that regards acoustic emission monitoring of a steel-concrete composite bridge.
I am analyzing some Power Density Spectrums that I calculated from the waveforms collected during the experimental program. Now, I am trying to classify some of them basing on Mean Frequency and occupied bandwidth. I have two main questions :
- Could someone gently suggest some literature reviews where I can read more about this topic?
- My actual classification method involves the inverse of the occupied bandwidth, so 1/obw. Does it have any meaning in the field? I mean, is it a feature that could be find anywhere? I also need some literature regarding it.
