Dear,
I am working in a project where i need to measure the density of the bone, using ultrasonic transducer, i have gone through TI website and found TDC 7200, TDC 1000 and MPS43x/C2000 block diagram, where both transmitter and receiver are on both the end of the object. Now if i use this technique i can measure only the distance of the object, but i need to measure the attenuation with the distance, so can guide me for this project.
