Arteche PQ, Inc. has introduced a complete range of active harmonic filters. This new filter product line achieves 5% total harmonic current distortion (THD) by monitoring the flow of harmonic ...

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 ...

The D68 series of 8-pole analog filters from Frequency Devices exhibits THD (total harmonic distortion) levels as low as -100 dB with near theoretical frequency response. Offered in low-pass and ...

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 ...

When harmonic content exceeds the recommended limits in IEEE 519 Recommended Practice and Requirements for Harmonic Control in Electric Power Systems, correction needs to be made to avoid interference ...

With the rising demand of non-linear type equipment and loads, mitigation of harmonics becomes increasingly important. If a harmonics study or testing indicates excessive harmonic levels or a ...

According to MarketsandMarkets™, the global Active Harmonic Filter Market is anticipated to grow from estimated USD 0.76 billion in 2025 to USD 1.11 billion by 2030, at a CAGR of 7.8% during the ...

Consumer requirement for fewer wires connecting their home entertainment systems is driving up the demand for wireless active speakers. In order to achieve the best audio quality from high end active ...

Over the years controversy has raged back and forth on whether brick wall filters used in digital audio (namely for CD playback systems) exhibit phase shifts in the audio band (20Hz to 20kHz). Audio ...

Michael Steffes challenges conventional approaches to Sallen Key Filter design. He says today's components and VFAs offer greater flexibility. This opinion piece links to more detailed explanations.
