Signal-to-Static Interference Ratio in Radio Telephony
Marius Latour · Proceedings of the IRE · 1924
Referring to Dr. Carson's paper on "Static-to-Signal Ratio," the author discloses a system of twin side-band radiotelephonic transmission, wherein the carrier component is suppressed, but which differs from other carrierless transmitting systems in that a homodyne receiver is not required. This last peculiarity makes the system particularly suitable for short wavelength transmission and especially so in view of the fact that the disadvantage of broader wave-length spectrum inherent to twin side-band transmission vanishes as the wave-length decreases.
