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 ...

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 ...

This paper considers linear regression models when neither the response variable nor the covariates can be directly observed, but are measured with multiplicative distortion measurement errors. To ...

Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

A couple weeks ago I built a simple 1KHz 6Vpp Sine Wave Generator from a handful of opamps and passives I had laying around. You can check out that project here. I thought it would be fun to quantify ...

TTi (Thurlby Thandar Instruments) has updated its AC1000 low-distortion power source to integrate with its latest power, harmonics and flicker analyser: the HA1600A. The new unit, designated AC1000A, ...

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 ...

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 ...
