Asymmetrical Sideband Transmission of Position Modulated Pulses

The present analysis is a theoretical examination of the asymmetrical sideband transmission in PPM systems. It is shown that the synchronously detected component of the envelope of an asymmetrically transmitted impulse can possess a steeper slope than the envelope itself and that over-all transient time of this component may be reduced. The effect of various degrees of transmission asymmetry is calculated for "squared cosine" type transmission-frequency characteristic. The conclusion is reached that for a given channel capacity an asymmetrical sideband transmission in PPM systems should be distinctly superior to a symmetrical one.
