ABSTRACT:
The present invention relates to a transmission method and device for efficient compression of digital data. The invention uses an optoelectronic coupler to receive light signals from a light transmitter at two bandwidths. A modulated signal generator is coupled to the transmitter which coverts voltage phase data signals to light signals. The data signals are modulated with a plurality of master profiles and subprofiles with different cycle time variations. The optoelectronic coupler has a pair of photodiodes. Light filters disposed on both diodes allow either the first or second bandwidth of light to pass. Conductors electrically couple the anode of the each photodiode to the cathode of the other photodiode which produce the voltage phase signal. A signal receiver is connected to the coupler and decodes the voltage-phase signal.
