A Note on the Reproduction of Pulses

The present note aims to demonstrate the relative significance of rise time and percentage energy content in the reproduction of rectangular pulses. Formulas are derived and their dependence upon various factors discussed. It is also shown that the rise time for periodic rectangular pulses is in general not the same as that for a step signal or a single transient pulse; it depends upon the number of harmonic components, the pulse repetition period, and the pulse duration in a more complicated way.
