## Homework Statement

This is not a HW problem. Just refreshing Tx line theory(reflections).

I have a pulse of 3.3v, period 36nsecs. (Ton=18ns, Toff=18ns) with a source impedance of 50 ohms, connected to a tx line of impedance 50 ohms. The load is high impedance or infinity.

So reflection at load is 1 and reflection at source is 0.

I drew the pulse waveform, but the pulse ends up at -1.65v. This does not agree with my Signal integrity simulation. So I wanted to double check if my work is right. Pls see attachment.

## Homework Equations

To draw bounce digram for a pulse, I made 2 sources. One with +3.3v and the other with -3.3v.

Also, when should I stop drawing the bounce diagram. In my case [tex]\Gamma[/tex]

_{g}is 0. so, after 3ns : ([tex]\Gamma[/tex]

_{L}* [tex]\Gamma[/tex]

_{g}* V1+) will be zero.

L is load and g is for generator.
