This assumption is demonstrated to be valid when the interharmonic source is an EAF which mainly produces modulation of the fundamental voltage in the frequency range from 0 to 20 Hz, that is to say modulations produced by interharmonics in the frequency range from 20 to 80 Hz.
In addition to the mean value, other features such as the start, minimum, or maximum value, or the modulation of the fundamental frequency may be determined.
For example, non-nested birds use a secured code for long-range propagation of sender's identity that relies on lower harmonics band and frequency modulation of the fundamental.
These structured RNA domains are widespread in bacteria and help in modulation of many fundamental biochemical pathways by sensing the metabolites such as adenine, guanine, FMN, glycine, and lysine [ 52].
LF is caused by the modulation of the supply fundamental voltage, which produces modulated light emissions whose severity, in terms of annoying effects on humans, depends on modulation amplitudes and frequencies as well as on lamp technologies [1].
As argued by [42], "the presence of amplitude modulation in bioelectrical processes is of fundamental nature, since it is a direct reflection of the control, synchronization, regulation, and intersystem interaction in the nervous and other body systems".
Complexes of co-expressed genes that were conserved across species or unique to a single species were identified, suggesting the existence of fundamental or species-specific modulation of gene expression controlling ESC pluripotency.
Muscarinic receptors are widely spread throughout the body, and are involved in the regulation of fundamental physiological processes, like the modulation of the heart rate, control of motor systems and modulation of learning and memory.
