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 ...

Wait a minute. Let’s see if I understand this. (Here I’m channeling you, the puzzled reader, after you’ve grabbed me in the coffee break of a Filter Wizard lecture morning). The frequency of the n th ...

In previous episodes of this long-running series looking at the world of high-quality audio, at every point we’ve stayed in the real world of physical audio hardware. From the human ear to the ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

Total harmonic distortion (THD), is a popular measure of nonlinearity of a device. Learn about the considerable flexibility in defining THD while providing a relatively simple way to orchestrate all ...

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 ...
