High-performance A-Weighting filter design emulates human ear
Articles  
11/22/2005   Post a comment
One way to evaluate and compare the audio performance of a circuit or piece of equipment is to use A-Weighting filters to emulate human perception of acoustic energy. Human hearing is most sensitive between 1kHz and 6kHz. Noise and distortion outside of this band, while undesirable, are less perceptible than noise within this band. The A-Weighting filter is designed to roughly replicate this psychoacoustic property.

Debugging by the book
Articles  
11/21/2005   Post a comment
Experienced engineers know that one key difference between a good designer and a good engineer is the ability of the engineer to debug circuits and systems. Debugging takes a special blend of knowledge, intuition, experience, rational analysis, out-of-the-box analysis, attention to detail, and predictive ability. Software debugging, of course, is a different beast than hardware debugging, although often in the early stages of debug, it’s hard to say with confidence which is the problem. In

There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
