In most media for communication, only a fixed range of frequencies is available for transmission. One way to communicate a message signal whose frequency spectrum does not fall within that fixed frequency range, or one that is otherwise unsuitable for the channel, is to alter a transmittable signal according to the information in your message signal. Thus the height of the generated ramp is determined by the delay between the pulses which indirectly follows the amplitude of the modulating signal.
