Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...

In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

Today we are going to explain about one more important concept – “FILTERS”. An electrical filter is a circuit, designed to reject all unwanted frequency components of an electrical signal and allows ...

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The ...

The IEEE's Applied Power Electronics Conference (APEC) is a must-go event for designers who need to keep up with the latest power-related technologies, products, and design practices. So, it's no ...

If you're responsible for maintaining quality power at a commercial facility and you've got a problem with harmonics, your best bet is to install a series of active filters. Opting for such filters ...
