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 ...

Audio notch filters help reveal low-level distortion products that would otherwise be hidden under a test signal in audio ...

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 ...

TDK Corporation presents the new MAF1608G noise suppression filter for audio lines. When inserted in audio lines, the new filter keeps THD+N of the audio signals to the world's lowest levels* of 0%.

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 ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...

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 ...

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 ...

This application note presents a total harmonic distortion (THD) test circuit that uses active noise amplification to eliminate the need for expensive and often ineffective external filters. Abstract: ...
