A property of a test system that allows the separation of signals from closely located discontinuities is known as what?

Discontinuity resolution is the property of a test system that enables it to distinguish between signals from closely spaced discontinuities. This characteristic is essential in non-destructive testing techniques, where the ability to detect and differentiate defects is crucial for assessing the integrity of materials and components.

A system with good discontinuity resolution can identify individual flaws even when they are in close proximity to each other, ensuring that the inspection results are accurate and reliable. This property is vital in situations where multiple defects might exist within a small area, allowing for more precise evaluations and preventing potential failures that could arise from undetected issues.

While other properties like dynamic range, sensitivity, and linearity are important in different contexts of measurement and testing, they do not specifically focus on the ability to differentiate between closely located discontinuities. Thus, discontinuity resolution is the most relevant term in this context, emphasizing the system's capability to effectively separate and identify different signals caused by nearby flaws.
