Introduction to analog to digital conversion

This video introduces the basic concept of analog to digital conversion.

I start by providing some motivation for such a conversion. I then plot out an example analog signal in the time domain, then discretize the signal in the dimensions of time (x-axis) and voltage (y-axis). I then show how we can find the closest discrete voltage value for each time interval, and how that value is transcribed into a digital signal on the same time axis.
