If the load impedance is not equal to the transmission line impedance, the wattmeter will indicate the amount of reflected power. |
The voltage ratios are equal to the turns ratios so we can just square the voltage ratios to get the impedance ratios. |
To measure body fatness, one may use dual energy x-ray absorptiometry, densitrometry or bioelectrical impedance. |
This feature sends a signal with a sharp edge down the transmission line and looks for reflections due to impedance imperfections. |
Body composition, including fat free mass, fat mass, was assessed by bioelectric impedance. |
After the leads for impedance cardiography were applied, we were unable to accurately collect and record bioimpedance data from 4 patients. |
