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 ...

The previous two chapters considered closely the distortion produced by amplifier output stages: a basically conventional but well designed Class-B amplifier with proper precautions taken against the ...

All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...

Sweden's Marten is well-regarded for its high-end speakers and takes a fair amount of pride in their audiophile-pleasing performance. So it comes as no surprise to learn that the company has decided ...

Digital predistortion is an approach to amplifier linearization that permits the efficiency of the multi-carrier amplifier to be dramatically increased. The principle of predistortion is intrinsically ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

It’s an understatement that [Troy] is not impressed with the distortion circuitry built into this guitar amp. He picked it up for $40 on Kijiji (basically local classified ads run by eBay) so he ...

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 ...

If you’ve ever glanced at the specifications sheet for an amplifier, one of the things you may have noticed is the amplifier’s class. Typically denoted by a letter or two, the most common amplifier ...

View PDF version of this article. What amplifiers are used to drive analog- to-digital converters (ADCs)? Possibilities include single-ended and differential inputs and outputs, plus voltage feedback ...
