In the wireless communication invented by human beings, the high-frequency electromagnetic (EM) waves do not contain information. They are responsible for carrying low frequency signals that encode information. For this reason, the high frequency waves are called "carrier waves". Two methods are commonly used for carrying signals: frequency modulation (FM) and amplitude modulation (AM). In AM, the amplitude of the carrier wave is varied in proportion to the waveform of the signal (Figure 15). When we tune in to a radio or television channel, the frequency of the channel refers to the carrier wave. A radio or television may receive the signals when its electronic circuit is "in resonance" with the frequency.

Interestingly, conscious perception seems to use a similar method for receiving information, not only the signals stimulated by sensory inputs, but also the messages from Heaven. Further details are presented in the next three chapters.
