Abstract
A method and apparatus for enhancing digital signal transmission is provided for (1) converting a digital signal to an enhanced analog signal having a specified polarity and angular velocity; (2) transmitting that enhanced analog signal from one electronic component to another electronic component; and (3) converting the enhanced analog signal back to a reconstituted digital signal. The enhanced analog signal comprises a smooth non-periodic function of voltage, current and time which preferably has the waveform of a versine function signal with specified polarity. A method of supplying power to remote locations of the apparatus for enhancing digital signals is also presented.
