固定增益时变频谱整形滤波器的理论研究

Theoretical Study on Time Variable Spectrum Shaping Filter With Fixed Gain,

在理论研究的基础上 ,文章提出用固定增益时变频谱整形滤波器来解决高频地震信号可记录性的新方案。并对滤波器的设计原理、工作过程及其对高频信号可记录性改善的效果作了详细分析。

On the basis of theoretical study,a new idea to solve the problem of high frequency signal recording by using time varying spectrum shaping filter with fixed gain was put forward, and the design principle and work flow on this filter were described in detail. At the same time,the capability of improving high frequency signal recording for this filter was also analysed. Results show that the limits of high frequency recording can be enhanced about one times.
