Analog vs. digital signals | Waves | Middle school physics | Khan Academy

I am so confused about the binary bit. How does 11000 equate to 16, 8, 4, 2, 1??

Thanks this was helpful

Why do you call this "Middle school physics." I'm 19 and want to learn about this now.

Sure middle schoolers should be taught this, but learning is for all ages.

That is pretty darn cool!

Another great video Sal!

I'm learning this in College. 💀 Not middle school. I feel dumb now.

Wonderful video, however, I learned this in Engineering school in college, it may have been tough to do in middle school :)

I’m doing A level physics in the UK and this video is very helpful. Thank you

Very interesting and it helps to understand the different videosystems out there for drone racing and freestyle. There is a trend towards digital videosystems right now which i now understand better, so thank you.

I thought you all were switching only to a grade school emphasis. However, if it will help me in medical school, please keep it coming!
