![]() ![]() ![]() How do you find the invertibility of a system? Both amplitude and phase may change, but the frequency does not change. What are the eigenfunctions of LTI systems?Ĭomplex exponential signals are known as eigenfunctions of the LTI systems, as the system output to these inputs equals the input multiplied by a constant factor. Changing the input in a linear way will change the output in the same linear way. Linear systems have the property that the output is linearly related to the input. LTI systems are those that are both linear and time-invariant. Examples of such systems are electrical circuits made up of resistors, inductors, and capacitors (RLC circuits). Any system that can be modeled as a linear differential equation with constant coefficients is an LTI system. LTI systems cannot produce frequency components that are not in the input.
