| Abstract: | Telemetering physiological signals from hospital patients by time-sharing infra-red radiation of fixed wavelength means that the limited time available for encoding each data channel imposes constraints on modulation methods. Analogue and digital modulation methods are compared and an unconventional pulse code is proposed. |
