* Select the number $(1,\ 2$, ... $)$ of the task to be processed. The number "0" corresponds to a „Reset”: Setting as at the program start.
* A task description is displayed. Parameter values are adjusted. Solution after pressing "Sample solution".
* Always interpret the graphics and the numerical results. The symbols $s_0$ (adjustable) and $s_{1}\equiv 0$ are equal probability.
* For space reasons, in some of the following questions and sample solutions we also use $\sigma = \sigma_\rm{AWGN}$ and $C = C_\rm{Rice}$.
