Deep-dive: AI Chatbot #gibberlink and #ggwave deep-dive with @NIApps #LabVIEW DSP

Shorter OVERVIEW video :: https://youtu.be/rTarhAfJvpc?si=jRPlr1upWcOEjhRT
We get a little deep here in the LabVIEW code and FSK based OFDM modulation that is used in the ggwave library for enabling Gibberlink communication.

We dive into concepts of how you go from ASCII characters to Bits to Symbols (frequencies) to an actual modulated signal via Inverse Fast Fourier Transform (IFFT) and back to bits form the Fast Fourier Transform (FFT).

In the end we still barely scratch the surface of these concepts, so the more you ask for in the comments, the more I'll come back to the well and fill up your bucket; Thanks!

Although we don't get all the way to demodulating the original content, we're on the doorstep of enabling this and if I get enough feedback, I'll make the part 2 deep dive

We're using #labview , @voicemeetersound5150 , and not much else to do a FAST deep dive investigation to the signals that these two separate systems are using to communicate to see if it's all a show, or are we really looking at the resurrection of our 1990s modem tones.
