For random variables (rv) $X$ and $Y$ on a space $\Omega$:
Assume the rv $X\sim f_0$ distributed and $Y(t)=c$ is a constant rv, i.e. $Y\sim \delta(t-c)$ using the $\delta$-distribution as a short notation. Using the convolution I get $X+c \sim f_0(y-c)$. (I think $X$ and $Y$ are independent as $\{t|Y(t) \in B\} = \Omega$ ($B$ is a Borel set in $\mathbb{R}$).)
Question: is this correct? If yes, ist there a good intuitive explanation for the shift?
