I am new to the wavelet field, and I am working with ultrasound signal. For my study, I needed to measure material using the pulse echo reflection method.
Basically, when the transducer transmits the signal, the signal will reflected back to the transducer. If material has a thickness, the signal will reflected for two sides which are the front and back. After receiving both signals, I need to differentiate both of them, however the received signals are overlayed.
I think by using a wavelet method, I can differentiate the signal, but the result that I got is unclear. Can anyone explain about this result? Is it that both signals can be differentiated?
