So what do the 5 harmonics mean in the real world? Stated succinctly, to make up a digital pulse it takes a minimum of five harmonics of a sine wave of the same frequency. So if one has a processor with its clock running at 2 GHz, it is processing or producing digital pulses at the rate of 2 billion pulses per second. After adding the five harmonics, this means that electronic circuitry will need to have the capacity to pass 2 x 5 or 10 GHz. If the circuitry was only capable of 2 GHz continuous wave, a 2 GHz pulse would be seriously rounded off to the point where the pulse becomes ineffective in carrying out its information transfer.
