Abstract: This contribution involves the generation, transmission, propagation and selective reception of electrical, magnetic or electromagnetic energy in the form of a halfwave sinusoidal pulse signal, from one location to another, whereby intelligence input for transmission is recovered from one sinusoidal pulse, or from a plurality of sinusoidal pulses. In a transmitter embodiment, one or more sinusoidal halfwave pulse generators are provided, where each pulse signal may be generated asynchronously, with varying polarity, duration and amplitude on a continuous serial sampled information basis. Complementary pulse signal filtering and recovering of transmitted intelligence is provided in a signal receiver embodiment. Another transmitter embodiment includes a software-driven signal synthesizing capability, wherein a plurality of timed sinusoidal halfways pulses are linearly summed as elementary signal components of an information-carrying propagable signal.
