摘要

This study addresses identification of the radio frequency range most promising for studying human respiration using a method based on radio waves. The potential of using the “Max Hold” and “Min Hold” modes of the spectrum analyzer for automation and simplification of measurements is demonstrated. Five breathing cycles are sufficient to obtain valid results.
