Question 54General Subjects - Assistant Engineer

The correct answer is A. Illustration EL-0124 depicts the proper method of circuit grounding for a low-level analog signal cable, which is to connect the cable shield to the system ground at one end only. This approach helps to minimize ground loop issues and signal interference, as per the best practices for analog signal transmission. The other options (B, C, and D) would not be considered the proper grounding method, as they either leave the shield unconnected or ground it at both ends, which can lead to ground loop problems and signal degradation.
