Abstract
A multiple rate waveshaping method and apparatus for converting transmission data into communications code synthesized waveforms having different protocol frequencies in the physical layer of the fast Ethernet utilizes two state machines which convert the transmission data into appropriate waveforms using predetermined wave shaping signals, the outputs of the state machines being multiplexed and transmitted over the Ethernet media using a common set of differential current sourced drivers.
