Abstract :
Digital transmission systems are usually designed around a nominal transmitted pulse shape. However, because of manufacturing tolerances, etc. there is not one nominal pulse shape but a family of pulses. This family may be specified by a mask or envelope of the extreme variations of the family from the nominal shape. The author determines the envelopes under two different constraints: the energy in the transmitted pulse is constrained, and the energy in a pulse that drives a pulse-shaping network is constrained. It is shown that both masks are related to a certain kernel function related to the impulse response function of the pulse-shaping network
