I put together this blog post that may be helpful to some in understanding 1-bit DPCM. When I was learning about it originally I had some problems finding illustrations of what was going on.
Here it is.

Good work dude. It's very easy to understand and suitable for beginners.
Excellent coverage! I like the graphs. You even covered how flat waves are encoded as a square wave at half the sample rate. Looking at your other blog posts, it's all very interesting for anyone interested in sound chip audio!
did you make the graphs with MATLAB? they look familiar...
I wish it was MATLAB, but I can't afford the $3000+ price tag. Instead I use GNU Octave. It's similar in theory and tries to be compatible with MATLAB scripts. It is far more fussy and missing a lot of features, but it is also free. For putting together stuff like this it's great.
