\begin{aufgabe}
\begin{enumerate}
\item (see assignment2\_4.m)
\item Phase Response is very small in the realm of $10^{-15}$. The signal contians multiple bigger spikes. \\

\item The magnitued seems to be repeating and the phase response seems to be mirrored accross the x and y axis.

\item original energy: 41343 \\ reverb energy: 2069.0506 \\ rir energy: $9.9997 \cdot 10^{3}$ \\
explanation: The rir energy is less than one which would explain why the outcoming signal is smaller than the original, because convulution scales proportionally.
