Abstract:
1. A transmission system for reduced energy transmission comprising: means for simultaneously encoding a group of parallel binary bits into a voltage amplitude signal having a phase, a superresonant filter having a local oscillator operating in phase with the voltage amplitude signal, the superresonant filter receiving the voltage amplitude signal and accumulating phase shift of samples with multiple iterations during at most a single period of a frequency and outputting a data signal the superresonant filter comprising: an adder for adding the voltage amplitude signal with a feedback signal; a squaring circuit for squaring the output of the adder; a first multiplier multiplying the squared output with an output of the local oscillator; a sign extracter to extract the sign of the first multiplier output; a square root circuit for taking the square root of the first multiplier output; a second multiplier for multiplying the output of the square root circuit and the output of the sign extracter; and a delay circuit for delaying the output of the second multiplier to produce the feedback signal.
