Recently in the forum a member questioned if there was a member that could provide the derivation of the transfer function for a Second-order Sallen-Key bandpass Active filter. I took on the challenge and the attached document is the results of my efforts. The answer I was able to obtain using...

(I originally posted this on the forums). Matlab is a proprietary numerical computing environment developed by the Mathworks which allows for matrix manipulation and mathematical analysis across a wide range of engineering and scientific disciplines. Through out my time using Matlab I have...

Attached is a solution of the unbalanced bridge circuit example present in the allaboutcircuits.com located at the link http://www.allaboutcircuits.com/vol_1/chpt_10/3.html The solution found in the AAC e-book has been solved using mesh analysis. I took on the challenge to solve the problem...

It has always been my contention that in order for a circuit analysis tool to be of any value to me, it must be scalable. This means it needs to solve the simpliest problem as well as the most complex problem by using the same repeatable algorithm. My experience has been that Millman's...
If you consider all blogs and the string's of intelligence that may exist.Then consider the number transistor's in a super micro-proceessor. (answer) ______ give details of the question,hint genesis of electronic need. I am exploring, I am no Einstein. I do not have the perfect question for the...

When I first wrote this I had been on this forum for about a month, and had made myself known. I've been drawing like crazy for the forums, submitted a new section for the eBook (ElectroStatic Discharge), and made a fair pest myself everywhere around here. It seems I made a big enough pest that...

I mentioned that I had a disagreement with an news article that reported that people associated Apple with innovation and IBM for something like reliability. Having delivered opinions on Apple, I start in on IBM. I do realize that the GMR head on hard drives has been an absolutely essential...
I went to the 33rd annual OKCA Knife Show yesterday. Once upon a time they billed themselves as "The largest knife show West of the Mississippi." The epithet is still accurate, but is now insufficient. "Largest knife show in America" would also be accurate, but insufficient. According to the...

Many people who use Matlab might not be aware of the File Exchange over at Matlab Central. As described on the Matlab site: Files are organised into 26 different categories depending on application. Files include Matlab functions, help files, cheat-sheets, and mini-projects. These files...

Dynamic methods, a feature of .NET Framework since v2.0, provide a way to create a method at program run time. When I learned about this feature, it looked like an opportunity for me to learn more about the intermediate language (IL) that is at the heart of .NET Framework programming. By way...

The e-book here at AAC is an unfinished and continuous piece of work. We get weekly recommendations for corrections and improvements to the e-book, and as such the e-book relies on the many people who use it to improve the content. Although the editing of the final version of the e-book is...

I have found that half the challenge and 100% of the fun of electronics is being able to accurately predict what is happening in one's circuit. Fortunately, there are many powerful circuit analysis techniques available for use in predicting what is occuring in one's circuit. Most of these...
Proof of principle worked at Radcon 5, now we'll be rolling out the first prototype at Norwescon. I nested wo pieces of C-purlin, (2" web w/ 1/5" legs) to make a tube. I've got six adjustable lamps attached to the back (daylight CFs in them) and eight high-Kelvin color LED lamps slung below...

Originally I posted this work around on the forums, I have had some positive feedback from the posts so in order to prevent it getting lost on the forums I thought it a good idea to post it up here. For those of you that might be using Matlab R2006 onwards there is a bug which means if you...

All work and no play makes for a dull Thingmaker. Wiring in the basement is coming along well enough, despite the many interruptions. Work is going well enough, despite the odd customs of Planet Intel. Remodeling a lab (cable tray moving) is on tap for the morrow, followed by can-lights and...
