    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Requesting Suggestions for Online Programs - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including responses to the original posts.

Hi, everybody.

I am looking for suggestions as to what kinds of (small) computer programs people would find handy.

As a hobby, I write small computer programs. I am now hoping to write a few for online use, posted as Javascript or PHP calculators.

So I am now looking for suggestions as to what kinds of calculators you would find useful.

Assume you do not have access to MATLAB or Maple. A hand calculator can do a lot, but it is not the most inconvenient interface. For example, a “3 Equations in 3 Unknowns” system can be programmed into many hand calculators, but a convenient web calculator, designed specifically for this particular problem is much nicer—quickly enter the numbers, click a “Solve” button, and you're done.

Do you find yourself doing the same calculations over and over again, wishing a simple program were available that could eliminate many of your keystrokes? If so please let me know about them.

Greetings DavidB:

I posted a link on the RF Cafe homepage directly to your topic to hopefully prompt a lot of response. It would be nice to get an extensive collection of online applets.

I will be glad to host them on RF Cafe if you do not have a website, or, let me know when you have some ready and I'll be glad to link to them.

Heres a suggestion. Make "real" versions of all the ones Kirt has that are done in that @%$^*!@ Microsoft OWC format. Sorry Kirt, but its MS I hate for creating proprietary stuff like that.

Some of those programs look pretty good. Do they get a lot of use? Which ones are the most popular? I have a few additional ones in mind. For example, Fourier Transforms, Bessel Functions, etc.

Somebody also suggested N Equation in N Unknowns in which the unknowns are complex. They mentioned such systems are solved when doing signal analysis. (I have no personal experience with these situations, so I am also curious: when DO such systems arise? A specific example would be much appreciated). Before going ahead to write such routines, I would like to get an idea how popular they would be.

In any case, I am still looking forward to receiving suggestions, perhaps with a brief comment about how popular you think it would be, the application in which you use it, etc.
