Yikes - why even mention the E and B fields? They aren't relevant to the rest of the article. A few hours playing with Sine and Cosine generators in GNU radio

Yikes - why even mention the E and B fields? They aren't relevant to the rest of the article.
A few hours playing with Sine and Cosine generators in GNU radio can take you from book knowledge of I/Q complex signals into fully grokking it. You don't even need a radio, just your existing audio I/O.
- ygritte 1y ago> existing audio I/O I never knew there even is such a thing. Where can I find it?
- galangalalgol 1y agoThere is a source block for your mic and or audio in. That was one of the first things I played with to understand sdr. I remember seeing a strong tone on a waterfall plot that I could not hear, thinking it was an articfact, then looking at the frequency and realizing I wouldn't be able to hear it. Turned out it was a crt TV. That kind of dates the story. Fun to be had.
- ygritte 1y agoDang, I just realized that I misread it. I was seeing "I/Q" where it says "I/O". My bad.
- dsp_man 1y agoI mentioned E and B fields so that the reader knows why we focus exclusively on sinusoids. Plus, linking the sinusoid to something we see in physics makes it more real.
