Analog Signal Processing – Class Knowtes

2nd_Butterworth

 

Thanks to all who showed up on Monday night (Feb 18th, 2013) for the signal processing class.  It was a lot of material to cover in one night, but I hope everyone at least learned (and retained) something.  I was asked by several people to post my lecture notes online so people can review them.  It took me awhile to go through my notes and clear them up (somewhat) for someone besides me reading through them.  Also, I had to erase and rewrite a bunch of stuff because they were too close to the edges and were being cut off by my scanner.  So that’s why it took so long.  Anyway, here are the notes, the notes for the pre-class Math Review, and the 8-page info packet that I passed out during class:

Analog_Signal_Processing-SK

ASP_Class_Packet-SK

ASP_Math_Review-SK

Now that the class is over, the next thing to do is figure out what class to teach next.  I noticed that many of the attendees enjoyed the filter design example we went over.  Perhaps we could do a short class on some practical Analog Filter Synthesis?  Some people have “thumbsed-up” the idea for doing a class on learning how to use LTSpice to build schematics & simulate circuits.  Recently, I’ve been reverse-engineering schematics from double-sided printed circuit boards in older consumer electronics.  I could demonstrate some techniques on how to do that.  Another idea is moving directly past the Analog Signal Processing class and going right into Digital Signal Processing.  All the same topics from analog appear in digital such as convolution, impulse response, frequency response, & transfer functions.  Except most of the integrals become discrete summations when in the digital domain.  There are neat topics specific to digital such as FIR filters and sample rate conversion, which I think are the most interesting.  Actually, the website Coursera just started a DSP class this week.  If you were at Monday’s class, the Coursera course should be much easier since most of the topics are similar, like I described above.  Check it out.

If you have any feedback on Monday’s class, ideas for other electronics classes, or any other comment, then please let us know.  If you see me at Pumping Station: One and remember what I look like, then feel free to talk to me in person.

Analog Game Night This Saturday!

Bring your favorites!

 

Anyone got a cool new game to play this holiday season? Wanna play it with a bunch of other gamer geeks? Got any awesome new minifigs, counters, or gaming dice sets that you want to show off to people for some geek cred? Just wanna hang out with some fun people and play games, drink beer, and eat some tasty snacks?
Bring  your favorite games over to Pumping Station: One this Saturday, the 5th, at 7pm and play the night away! As usual, all games are welcome [even cuddle dice, though you may have a hard time finding people to play with], major gamercred to homemade games.

See you there!
