Abstract:
A telemetry system for transmitting a plurality of sensor signals comprising:a pseudo random number generator generating a PRN signal;a clock generating a clock signal;a plurality of transmitters corresponding to the plurality of sensor signals, each one of the plurality of transmitters receiving the PRN signal, the clock signal and the sensor signal corresponding to the transmitter, the transmitter modulating the PRN signal with the sensor signal at a distinct cycle of the clock signal, the transmitter outputting the modulated PRN signal;a data channel receiving the modulated PRN signal outputs from each one of the transmitters and summing the modulated PRN signal outputs; anda receiver receiving the PRN signal, the clock signal and the summed modulated PRN signals, the receiver splitting the summed modulated PRN signals into a plurality of split modulated PRN signals corresponding to the plurality of sensor signals, combining each one of the plurality of split modulated PRN signals with a PRN signal shifted to the distinct clock cycle corresponding to one of the plurality of sensor signals and demodulating the combined signals to output the plurality of sensor signals.
