摘　　要：在简要介绍模拟滤波器数字逼近的几种方法的基础上，着重分析双线性变换法的原理、算法及软件实现方法。本方法简化了模拟滤波器的数字化，也为分析数字滤波器的稳定性能提供了方便。The digital filter is widely used in geoscientific instruments. Based on the brief recommendation of the ways to transfer analog filters to digital ones, the principle, calculating method and software realization of bilinear transformation are emphatically analyzed. The proposed method simplifies the digitization of analog filters, and also provides convenience for analysis of the stability of digital filters.
