Abstract
The present invention is an apparatus and method for increasing the amount of data on a transmission path on a printed circuit board. Conventional methods allow only one data signal to be transmitted on the transmission path. The present invention uses multiple transmitters to modulate multiple data signals to form multiple modulated signals. The modulated signals are transmitted, possibly simultaneously, on the transmission path to receivers configured to demodulate individual modulated signals and recover the original data signals.
