Waves may be graphed as a function of time or distance. A single frequency wave will appear as a sine wave (sinusoid) in either case. From the distance graph the wavelength may be determined. From the time graph, the period and the frequency can be obtained. From both together, the wave speed can be determined. Frequency is cycles per second ... Frequency and load. The primary reason for accurate frequency control is to allow the flow of alternating current power from multiple generators through the network to be controlled. The trend in system frequency is a measure of mismatch between demand and generation, and so is a necessary parameter for load control in interconnected systems.
This suppresses the carrier frequency in the high-frequency range just as the demodulation circuit does in man-made receivers. What remains is the signal impressed on the carrier frequency, e.g. in the low frequency ELF range. This is also the frequency range at which our own nervous system normally works.
