Here's a larger 16 sample memory depth, 4-bit resolution, 8 bytes storage space AWG. I've also added some output filtering and amplifier.
I preloaded an AM wave, but AWGs can produce lots of different types of signals. Here are a few others you can try. Enter the information into the logic buttons.
Sine. Square. Ringing Square. Triangle.

I was going to use logic gates, but it became SO slow it was practically impossible to see what was happening. I discovered I can use resistors and VCVS to make huge OR gates that still keep running speeds up!
P.S. Please can EveryCircuit developers fix the slow logic gates?
