Abstract
Delay transmission lines are widely used in pulse technique, which is extensively applied in many electronic applications, such as, distributed amplifiers, pulse coders and decoders, precise time meausurements, radar, television, digital computer systems, and cathode ray oscilloscopes. an ideal delay transmission line, should presserve the shape of the input pulse at its output. This necessitates that the transmission should not add an appreciable rise time to the output pulse, and should have a constant frequency response, and a constant group time delay, (G.T.D) response, phase distortion severely affects the shape of pulses, but it can be held within acceptable limits either by conservative design or by equalizing means. Special care should be taken when designing transmission lines, to delay pulses of small rise time and narrow pulse width. A given delay can be obtained with less attenuation and smaller size with a lumped parameter line, than with a distributed - parameter one. However, the characteristic of transmission lines with lumped constants, on the contrary of transmission lines with distributed constants.
