longitudinal modulation

Longitudinal modulation involves adjusting a signal's properties—such as its amplitude, phase, or frequency—as it travels forward along a specific path. Think of it like fine-tuning a radio signal so that its strength or timing varies steadily over distance or time to improve communication, reduce interference, or encode information. This technique is used in various fields like telecommunications and physics to control how signals propagate, enhance data transmission, or influence wave behavior efficiently.
