The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown, 1 but they are not common.

Made to measure: the 603A phantom from CIRS is designed specifically for SRS planning and comprises a tissue-equivalent, anthropomorphic design that can be imaged using X-ray, CT and a range of MRI ...

When we think about signals and systems, we often do so with an emphasis on creating and transmitting signals with specific characteristics. That is, we want the signal to have some desired amplitude, ...

Recently I've done a collection of measurements and tests on interconnect cables to see what I could find that would explain the sonic differences that many people, including myself, have grown ...

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 ...

Aluminum’s unique properties, such as high thermal conductivity, rapid heat dissipation, and its persistent oxide layer, mean ...

If you follow audiophile reviewers, you’ll know that their stock-in trade is a very fancy way of saying absolutely nothing of quantifiable substance about the subject while sounding knowledgeable ...
