Fault isolation through signal analysis

Definition

Fault isolation through signal analysis refers to the process of identifying and pinpointing the source of a fault in a system by examining the signals and data it generates. This technique is crucial for maintaining system reliability and safety, as it allows for timely diagnosis and targeted interventions to prevent further complications. By analyzing signals, engineers can differentiate between normal operating conditions and anomalies, leading to effective fault isolation.
