Abstract :
Pulse generation from charged transmission lines or other charged sources are well known, however such circuits are not reverse matched. This work identifies a method of constructing different types of pulse generators, while inserting a constant 2/1 voltage ratio loss includes complete absorption of energy reflected back into them. Some measurement systems require that reflections from a load of variable impedance be absorbed. By inserting a Zr resistor in series with source and a parallel shunt circuit composed of elements complimentary to those charged, which has the same Zr series resistor. This circuit reverses the reflection absorption method introduced by Bode in 1945 with complete absorption and a fixed 2/1 voltage attenuation. Reflections for dynamic impedance loads which vary during the pulse are absorbed.
