Let's see if I got this correct . . .
So you have the I & Q signals that are at audio frequencies (about what frequencies are they) . . . going into your PC soundcards.
Once this gets into your PC via the soundcards . . . it gets changed ( detected ) into "usable" content via the SDR software.
I guess that the SDR software uses programming language to do this, does anybody know what programming language?
I know alittle about Python, is it a common language or something new & special for this function, acting as a detector? If it is new language, what is it called?
Does anybody know of a website that explains this all . . . in depth.
Thanks
