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 ...

No, it's not just a simple distortion correction filter. A Google research team has been working on eliminating the face-stretching distortion you get from wide angle lenses, without the ugly bending ...

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 ...

Researchers in Malaysia have published a study of total harmonic distortion (THD) reduction techniques in PV systems and claim to have found an holistic and systematic approach. The paper Advances in ...

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 D68 series of analog filters from Frequency Devices have Total Harmonic Distortion levels as low as -100 dB with near theoretical frequency responses and low noise. The D68 filters are available ...

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 ...
