In communications, unwanted frequencies that are generated as multiples of the original frequency due to irregularities in the transmission line. In audio amplifiers, harmonic distortion comes from ...

We all know what distortion sounds like. We’ve heard it in heavy metal tunes, cheap iPod docks and the crummy speakers at Taco Bell drive-thrus. And we’ve all read distortion specs on things like ...

Figure 1a illustrates a typical transformer having a primary to secondary turns ratio of 1:N and a primary inductance of LP. In the real world, however, transformers aren't ideal, and they can ...

A detailed analysis of the total harmonic distortion for a nonisolated boost topology with average current-mode control using the UC1854A and the UCC3817. IAC = Current reference. Ideally, IAC is a ...

The proliferation of end-use electrical and electronic loads in customer facilities — residential, commercial, and industrial — is not slowing down. Despite economic pressures, utility customers are ...

Sold as ‘kits’, the self-assembly aspect of the Nu:Tekt TR-S Power Tube Reactor and HD-S Harmonic Distortion is actually limited to screwing on the bottom plate, sticking four rubber feet on and ...

The project was built and designed to measure the quality of AC voltage using a harmonic distortion meter based on PIC18F2550. The project was built and designed to measure the quality of AC voltage ...

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: ...

Tektronix must have been quite a place to work back in the 1980s. The company offered a bewildering selection of test equipment, and while the digital age was creeping in, much of their gear was still ...
