Transient analysis is a type of analysis in engineering and physics that focuses on studying the behavior of a system over a short period of time in response to a sudden change or disturbance. This type of analysis is used to understand how a system reacts to transient events such as sudden voltage changes, electrical pulses, mechanical shocks, or other abrupt changes in input. By analyzing system behavior during transient events, engineers and scientists can gain insights into the performance, stability, and response of the system under dynamic conditions. Transient analysis is commonly used in fields such as electrical engineering, mechanical engineering, control systems, and signal processing.
