Solution for Task 1:<br />

First right click on the symbol of the<br />

voltage source to open the property<br />

menu. Then fill the PWL-list with<br />

the informations about the<br />

additional points and value pairs<br />

(use the button “Additional PWL<br />

Points”):<br />

0 0<br />

1m 0<br />

1,000001m 1000000<br />

1,001001m 1000000<br />

1,001002m 0<br />

When simulating input and output voltage you get this screen where only the Dirac impulse with its amplitude of 1<br />

Megavolt can be seen:<br />

Use the zoom function for other details, because the system’s response has only an amplitude of 10KV. So<br />

change the scaling of the two axis to see the response curve -- and afterward have a look at the solution on the<br />

following page.<br />
