Terahertz Engineering

Definition

Sensitivity analysis is a technique used to determine how different values of an independent variable impact a particular dependent variable under a given set of assumptions. This method helps in understanding the influence of variability in input parameters on the output, allowing for better decision-making and optimization in the design and analysis of systems.
