Abstract:

It is well known that the fall time of a pulse generated by means of a Pulse Forming Line PFL, of either the distributed or lumped parameter type, is longer than the rise time by approximately a, rule of thumb, factor of two. The reason for this lengthening of the fall time is the result of the wave reflected back on the line during the rise time, which is then again reflected from the far end of the line and propagates to the load end where it affects the fall time of the pulse to the load. If a switch and termination is placed at the far end of the PFL and the switch is synchronized to close when the reflection from the load end of the line arrives, then it is possible to affect the pulse fall time. By choosing the value of the termination the fall time can be adjusted over a range from about twice the rise time to a speed which is much faster, typically about 40 percent of the rise time.
