A continuous-time input signal

x(t)

is an eigen function of an LTI system, if the output is

$k x(t)$ , where is an eigenvalue.
$k e^{j u t} x(t)$ , where is an eigenvalue and is a complex exponential signal.
$x(t) e^{j a t}$ , where $e^{j a t}$ is a complex exponential signal.
$k H(ω)$ , where $k$ is an eigenvalue and $H(ω)$ is a frequency response of the system.
