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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Engineering Humor - RF CafeTake a break from the drudgery with some of these jokes, song parodies, anecdotes and assorted humor that has been collected from friends & from websites across the Internet. This humor is light-hearted and sometimes slightly offensive to the easily-offended, so you are forewarned. I have taken care to censor "humor" with reproductive function innuendo and hateful tirades, so it is all workplace-safe. I have also tried to warn of any links that will result in audio clips so you can take appropriate precautions. Please send any potential candidates for this humor page to the e-mail link above.

RF Cafe - Lissajous pattern on an oscilloscope (Wikipedia image)RF Cafe - Spirograph, by HasbroBack in the early days of creating "art" with waveforms, the best that could be done was making some spiffy Lissajous patterns on an oscilloscope by driving the x- and y- axes with various inputs. Lissajous curves are the ones that look like they were made with a child's Spirograph. Really high-end waveform artists figured out how to drive the z-axis (intensity) to blank out the pattern in the right places to draw more sophisticated pictures. As is usually the case, with the passage of time comes an evolution to higher-order applications, like orchestrated Lissajous shows.

Sometime, however, artwork appears quite by accident and takes a sharp-eyed observer to recognize the image for what it is. Think of all the images of Mary that have been found everywhere from a stained subway wall to a grilled cheese sandwich.

Now, RF Cafe visitor Tony T. has had just such a revelation while viewing a multi-carrier waveform for WCDMA on an Agilent spectrum analyzer. He has titled it, "One Finger Salute." Maybe that waveform was trying to tell him something...

There are many videos posted online from people who have created Lissajous "shows."
