  • Narrowband FFT Analysis in a Hand-held Analyzer – A Product Engineer’s Tale

    “Wheeeeeeek… When pronounced in a falsetto voice, that’s the noise the brand new product makes. Hurts the ears, I’ve heard it so many times. Always the same pitch, at least to my ears. The unusual thing is that not all the units make the sound. The helical gear drive is supposed to be as quiet as possible and now I’ve got to fi gure out what the problem is.” If the above strikes a chord, then ...
