Measuring an op amp’s THD(total harmonic distortion) at frequenciesbelow 100 kHz is problematicbecause modern amplifiers have a THDrating that is much lower than that ofmost test equipment. 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 ...

Depending on the low-distortion needs of an application, the system engineer can choose from plenty of signal amplifiers. The first step in making the right choice is to understand the typical ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...

Q: A quick question. Isn't THD important in the sound quality of a receiver? The lower the better? Also, when you see the 20 - 20,000 Hz versus 40 - 20,000 Hz, the higher number 40 will affect the ...

Setting a benchmark for performance, the LM4562 audio op amp specifies a THD+N figure of 0.00003%. The device combines a 6-MHz, unity-gain bandwidth operational amplifier with a proprietary ...

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 ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

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 ...
