How can the total response of a linear system be analyzed according to superposition?

• A. By evaluating it only under specific conditions
• B. By summing the responses to individual stimuli
• C. By focusing solely on the final response
• D. By monitoring only the initial stimuli

Answer: (B)

The total response of a linear system can be analyzed using the principle of superposition by summing the responses to individual stimuli. This principle states that in a linear system, the response caused by multiple inputs is equal to the sum of the responses that would have been caused by each input individually. In other words, if you apply two or more stimuli to a linear system, you can determine the overall response by calculating each stimulus's response separately and then adding those responses together. This method is particularly powerful because it simplifies the analysis of complex systems. Rather than dealing with the entire system response in one go, you break it down into manageable parts. Each individual input's effect can be understood on its own, and then these effects can be integrated to understand the complete system behavior. This principle is foundational in electrical engineering, control systems, and many other fields, allowing engineers to design and analyze systems methodically.
