Arbitrary Waveform Generator - Upgrade

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. 0000 0000 1111 0000 0001 0000 1001 0001 0010 0000 1101 0010 0100 0000 1010 0011 0111 0000 1011 0100 1011 0000 1011 0101 1101 0000 1011 0110 1110 0000 1011 0111 1111 1111 0000 1000 1110 1111 0110 0111 1101 1111 0001 0110 1011 1111 0100 0101 0111 1111 0011 0100 0100 1111 0011 0011 0010 1111 0011 0010 0001 1111 0011 0001 Feel free to experiment with your own! If you'd like more info on how an AWG works, check into my first circuit: https://everycircuit.com/circuit/6641355690082304 Variable frequency version: https://everycircuit.com/circuit/5404744524496896 DDS https://everycircuit.com/circuit/6214446053326848 NCO: https://everycircuit.com/circuit/5760185112723456 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?
