Sometimes it doesn’t hurt to revisit some of the basic building blocks that form the foundation of what we do. And so we have gathered together a few of our most popular past articles that deal with the fundamental aspects of measuring and analysing noise and vibration data. Please leave a comment if you have a favourite. Or, if you think there is a topic we could cover in future posts, then let us know. The links to the articles start right under the line below, so, let’s go ‘back to basics’…
Fourier analysis takes a signal and represents it either as a series of cosines (real part) and sines (imaginary part) or as a cosine with phase (modulus and phase form). As an…
The “standard” centre frequencies for 1/3 octave bands are based upon the Preferred Numbers. These date from the 19th century when Col. Charles Renard (1849–1905) was given the…
A resonance occurs when a structure or material naturally oscillates at a high amplitude at a specific frequency. This frequency is known as a structural resonant frequency…

Could you send the basics article as a single .pdf to be read offline?
I can not read well from the screen.
You can find my articles online under NVH Simulation at my website.
Thanks,

Hi Alan. I’m afraid we don’t have these particular articles readily to hand in PDF format. However, I believe they will all be included in the next edition of our Handbook that is due out later this year. The new edition will be announced here on the blog. So keep and eye out and request a copy to get all theses articles in print or PDF form.
Thanks for notify us with this post. This post can help me in understand all the basics.
