Practice Question on "Signals and Systems"
Topic: System Invertibility
Question
The input x(t) and the output y(t) of a system are related by the equation
$ y(t)=\left\{ \begin{array}{ll} 0, & t<0 \\ x(t), & t \geq 0 \end{array} \right. $
Is the system invertible (yes/no)? If you answered "yes", find the inverse of this system. If you answered "no", give a mathematical proof that the system is not invertible.
