Question
Determine the properties satisfied by LTI system
Group of answer choices
- Both
- Linearity
- Time invariance
- None
Solution
An LTI (Linear Time-Invariant) system, as the name suggests, satisfies two main properties:
-
Linearity: This property states that the response of an LTI system to a linear combination of inputs is the same linear combination of the responses to those inputs. In other words, if you have two inputs x1(t) and x2(t) with responses y1(t) and y2(t) respectively, then for any two constants a and b, the system's response to ax1(t) + bx2(t) will be ay1(t) + by2(t).
-
Time Invariance: This property states that the behavior and characteristics of the system are constant over time. This means that the response of the system to a particular input does not depend on when the input is applied. If x(t) produces output y(t), then x(t-T) will produce output y(t-T) for any time shift T.
So, an LTI system satisfies both Linearity and Time invariance properties.
