Abstract

The present invention provides for a methods, system, and apparatus relating to data transmission. One method of the present invention includes representing data using at least one pulse based on a Gaussian wave form, sending the at least one pulse over an electrically conductive guided media, and recovering the data from the at least one pulse. The present invention can be used in conjunction with telephony applications, cable tv applications, and data bus applications.
