In previous episodes of this long-running series looking at the world of high-quality audio, at every point we’ve stayed in ...

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 ...

Third harmonic distortion in amplifiers can be dramatically cut with a new circuit configuration, claims UK feedback specialist Dr Aubrey Sandman. With a simple inverting amplifier, third harmonic ...

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 ...

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 ...

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 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 ...
