深井地震观测可以排除地面噪声干扰的影响，提高观测的信噪比，应用前景广泛。文中介绍基于DSP的深井宽频带地震计，总体介绍其特点、组成、原理，并对某些关键问题进行阐述，说明各部分的具体实现方案，并研制初步样机。

Borehole observation can eliminate the infection of environment noise，improve the signalnoise ratio. In this paper, a new borehole broadband seismometer which is based on DSP microprocessor is described. Firstly, the character，component and theory of this seismometer is described, then some key techniques are expatiated, and finally, a solution of the new model of borehole broadband seismometer is illuminated.
