| Abstract: | With the application scope of the superconducting technology continues to expand in recent years,the impact of superconducting technology has spread to all the areas. Through analyzing the properties of the superconductor resistance,this paper has given a new superconductor resistance measurement program based on the weak signal detection. It used a high-performance DSP chips to make the correlated detection of the superconductor resistance to be realized. And it used a single-chip with a double-integrating... |
