This paper examines the impact of asymmetric pulses in NRZ waveforms generated bymaximum-length sequences and used in spread spectrum systems. The data asymmetryphenomenon is produced by differential propagation delays through logic circuits in thepayloads. A model of three elementary pulse shapes is employed to characterize thesignal source and the occurrence probabilities for each is calculated. The autocorrelationfunction of the waveform is eventually obtained taking into account the asymmetry, andsome numerical evaluations are finally presented to show the deviation from thetheoretic case where no asymmetry is considered
