Two methods for measuring thermal distortion of antenna dishes under simulated space conditions are described: Photogrammetry Holography With modern photogrammetry an absolute resolution of 20 μm at 1 ...

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 ...

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 ...

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 ...

Theory suggests that optimal contracts should include many contingencies to achieve optimal risk sharing. However, in practice, few contracts are as complex as theory suggests. This paper develops a ...

Revision of Chapter 14.1 of the API Manual of Petroleum Measurement Standards (MPMS) was published in June 2001. This revision is the result of 7 years of an extensive natural gas sampling methods ...
