Exercises

* First, select the number $(1,\ 2, \text{...} \ )$ of the task to be processed. The number $0$ corresponds to a "Reset": Same setting as at program start.
* A task description is displayed. The parameter values are adjusted. Solution after pressing "Show Solution".
* Both the input signal $x(t)$ and the impulse response $h(t)$ of the filter are are normalized, dimensionless and energy-limited ("time-limited pulses").
