[QUOTE="Vipersan, post: 964486, member: 325666"] TBH TJ ...not as complicated as it looks .. If you have ever used a communications receiver ...you'll know there are switches and buttons to insert various bandpass filters ..oscillators to reinsert carriers ...and switch between various modulation forms ..AM /FM ...to give 2 simple examples.. The difference is that on Software defined radio ...the buttons and switches are replaced with a GUI ....and switched electronically .. Thats basically it.. The coloured 'waterfall' as it is referred to is just a graphical representation in real time of a section of the spectrum as it progresses ...and as such has a great advantage over conventional receivers in that it doesn't require physical knob twiddling to see everything in that chunk of spectrum ...and you can pounce instantly on an interesting peak ...without actually having to turn the dial and tune to it .. pretty good eh' and thats just radio ...with the plugins and addons ...so much more is possible ...by analysing and decoding thos signals (digital and analogue) For example you could intercept and decode a pager signal (digital) ...or ...decode a morse code signal (analogue) without even knowing morse... .--. .-. . - - -.-- / -.-. --- --- .-.. / . .... / ..--.. :) [/QUOTE]
