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 ...

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 ...

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 ...

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%.

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 ...

Sinevibes’ latest venture is a multi-algorithm distortion processor known as Corrosion. Offering seven distortion curves, this also includes a pre-distortion filter for tone shaping, and a crossover ...

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: ...

Bending, twisting and distorting images can sometimes produce remarkably creative works of art. For example, you can expand the center of a basic circle shape to produce a bulge effect. GIMP, a free ...
