So I am trying to figure out whether $e^{\varphi-1}$ is a characteristic function given that $\varphi$ is. I know that linear combinations of characteristic functions and the real part of a characteristic function are characteristic functions. I would like to figure this one out by myself so just some small hints would be appreciated. How do I chose the random variable $Y$ for this function?
