By tracking this ratio over time, he can determine how long gas has taken to reach the surface and gain clues to the chemical, thermal, and mechanical state of the rocks the gas is passing through.
The effect of thermal noise and vehicle dynamics on carrier tracking loop are also analyzed, and the optimal bandwidth of carrier tracking loop is obtained.
并以相位跟踪环路为例分析了热噪声及载体动态性对环路的影响，得出了环路设计的最佳带宽。
