According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

In the 1960s, mainframe computers took up entire rooms. By the 1980s, there were individual workstations and just a few decades later, laptops and smartphones became ubiquitous. Today’s technology is ...

In Part 1 (click here), we learned how an old technique known as servo feedback can remove dc offsets in a dc-coupled gain block, without putting any components, especially capacitors, in the ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...

Many analog signal-chain circuits require ac-coupling to eliminate unwanted dc voltages or offsets. The simplest means to ac-couple is to use a capacitor in series with the signal path, thus forming a ...
