What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...

One of the most often mentioned and misunderstood power quality issues we see with commercial, industrial, and power-generating electrical equipment is harmonics. Since it’s impossible to explain the ...

Figure | Schematic of the experimental configuration to generate and detect THz third harmonic generation. A multicycle driving field at the frequency w is transmitted through a lowpass filter. Inside ...

For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the nonlinear junction ...

The auditory system encodes sound by decomposing the amplitude signal arriving at the ear into multiple frequency bands whose center frequencies and bandwidths are approximately exponential functions ...
