This is very useful for my learning.

I want to take this a bit farther. We have designed and tested a transceiver with dual DDS chips and a very linear summer for VCO FM/FM modulation. Now I need to make it all digital. The secondary sine waveform comes from the DSP but the primary triangle is embedded in the VCO chip. How do I combine them properly in the VCO for FM/FM modulation? I am confused on how to execute this plan.
Thanks.
Marty
