Electrical transmission lines, to transmit high frequency signals, a rectangular pulse, pulse generator, pulse forming device, function as a filter, filter, noise suppression filter.
1. By charging the transmission line and then discharging it into a resistive load, a rectangular pulse equal in length to twice the electrical length of the line can be obtained.
2. By cuttin the free end of the transmission line, a minimum in the strength of the signal observed at a receiver can be found.
