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 ...

producing the frequency predicted by equation (8). Higher-order harmonics can be calculated similarly. As an example, Figure 1 shows the output spectrum for the quad-channel, 16-bit, 2.5 Gsps DAC38J84 ...

Comb-based optical frequency metrology and atom clocks have pushed the measurement of time and frequency to unprecedented precision in recent decades 1. The recently emerged miniature ...

Industrial and commercial customers constantly scrutinize their monthly electrical usage, looking for ways to save money. Installing power factor correction capacitors can reduce costly penalties ...

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 ...

Musical instruments and throats create different notes by making the air around them vibrate at particular frequencies (check out part one to find out how they do it). When you pluck the A string on a ...

The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...
