Hi Jeffrey
Great to see you doing a modulator. You do like pushing the limits of your resources
. I am surprised that your DAC is working at so much over spec.
"I'd made an elementary error. Forgot to invert the MSB before sending the signal to the DAC."
Snap! did the very same thing. I do add "10000000000000" to the sine table's output. I had thought of it as adding 50% of the sine tables max value. But as you have said all I am really doing in inverting the MSB bit.
Looking forward to your endeavors with great interest.
