Abstract
In today's world, the development of economy has led to the continuous development and evolution of science and technology. Computer technology and large-scale integration technology have been well developed and applied, followed by the technology of digital signal processing DSP production and application. In the field of logging, the application function of this technology plays a key role. It not only allows the imaging logging technology to be further developed, but also enables fast and accurate processing of downhole signals. Therefore, among many logging tools today, digital signal processing DSPs have been widely used, and their functions have been fully utilized. This paper analyzes the application of signal processor DSP in logging instruments. It is hoped that it can play a reference role in the good application and development of logging instruments.
