Abstract

An embodiment provides a pulse harmonic modulation method comprising transmitting a first data initiation pulse to an input of a first resonant circuit thereby creating an oscillating waveform at an output of a second resonant circuit and transmitting a first modifying pulse to the input of the first resonant circuit. The first modifying pulse can modify a first portion of the oscillating waveform.
