MORE VIDS - JFETS

here's more electronic theory videos, this time JFETS.

SOME INTERESTING TECH VIDEOS

here's a few interesting audio electronics related vids i pulled off the net.  i haven't had a chance to check them out yet, but i thought it couldn't hurt to post them anyway.  check out the other videos on the channels of the posters, there is some good stuff there as well.  

cheers!

LISSAJOUS FIGURE VID

browsing the really cool EXPERIMENTALIST ANONYMOUS BLOG, i found this great video of a LISSAJOUS FIGURE portrayed on an oscilloscope. from what i gather, a lissajous figure can be generated using a scope by injecting one wave ionto the x axis, and another onto the y axis. summing them together, you get this 3D effect. the maker of the video put the left channel through the x axis, and the right through the y, all the while tweaking multiple effects. as i finally picked up a scope recently, i find this sort of thing fascinating. unfortunately, the cheapo 40 dollar scope i got only has a single channel, so you won't be seeing any lissajous figures from me in the near future.
