Someone commented below that the static must be cell phone interference. Wrong! It's his lavalier microphone rubbing against his lab coat. Or possible a bad wire in the mic that is shorting out as it moves. Notice the correlation between his movements and the noise. This could have been avoided by pinning the microphone somewhere else on his body, replacing the mic (if it's a shorted wire) or using a small pop filter on the mic.
Although this video was uploaded 4 years ago, I'm hoping someone is maybe reading the comments still and could answer a question on the lecture. Basically I'm just watching this class online because I need something to do while I do my boring office job so my brain doesn't melt. That being said, I have very little understanding of electronics stuff outside of this lecture series. Most of the time the teacher does a great job of giving real world examples of why the type of circuit is being used. In this lecture he said that the capacitor is used for low frequency and the resistor for high frequency and compared it to speakers. That was great. Then he goes further into having a circuit powered by ac and dc among a bunch of other sample circuits. My question is could someone give some real world examples of what filtering, coupling, and phase shift are used for? I guess I could start some google research but I figured why not try here first.
+Carley Winn I found these, and shows basic schematic representations:www.allaboutcircuits.com/textbook/experiments/chpt-5/rectifier-filter-circuit/www.electronics-tutorials.ws/oscillator/rc_oscillator.htmlHope these may answer your questions. Or go to a stereo shop, and ask about their crossovers, they use filters.
Real shame the audio is so bad on some of these ... great resource otherwise.

can someone go back in time and tell Joe to to fix the mic?
ELEC 110 Chapter 15 - Capacitive AC Circuits
Dam that static is driving me nuts. arrrrrr. Must be someones cell phone interfering. I wish it could be redone. You are the bomb Dave.
You would think being the instructor he would have his act together on the audio.
Found Chapter 15 finally
Great content, but the audio problems make much of this video unwatchable. Such a shame.
Excellent series, shame about the interference :(
Electronics professor with serious audio issues. What's wrong with this picture?
Why is there static ;(
Ya there is static
what the f'n c is that static all about anyway.
I thought that was really funny. Still the best though.
static on your vid mate, ironic.
