Transmission lines terminated with a Capacitor load, or a R

[QT_GIRL]

Hi guys does anybody know in Transmission lines what happens when you send a pulse into a transmission line terminated with a Capacitor load, or a Resistor load?
Thanks

For short time intervalls, the TL output acts like a resistor equal to its impedance, the waveform at the capacitor shows low-pass behaviour. Because of impedance mismatching, part of the pulse is reflected.

With resistive load, you get a real valued reflection coefficient r = (R-ZL)/(R+ZL) and respective behaviour, as shown in any electronics text book. With R=ZL, the pulse is completely absorbed.

Is it pulse or impulse? Am trying to understand the problem.
If pulse then what is the pulse width?

try to find ur answer in Senema Book
he has defined all the three cases

the Reflection for Capacitive will have a diffferent peak
