Active filters and advanced signal processing techniques are at the forefront of modern electronic system design, enabling precise manipulation of analogue signals for a variety of applications. Owing ...

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 ...

The EPCOS PQSine™ series of active harmonic filters from TDK Corp. are designed to optimize power quality. The modular filter systems are designed for 3-phase networks with and without neutral ...

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 ...
