Well Software, duh ;).
The point I was sarcastically making was that even in SDRs you still have a downconversion via either Direct Converting or SuperHet to baseband so your signals are in the right frequency reference that you don't completely saturate your DSP/FPGA/CPU.
I love software as much as anyone else but just saying that you can do everything in SW is a bit disingenuous.
- jacquesm 9y agoBut nobody said that. I wrote "So now anything that I do that has to have an effect in the real world is put together with the absolute minimum in interface hardware and the remainder is software." and the other person wrote "virtually".
- vvanders 9y agoI was replying to the second, just adding a "virtually" doesn't absolve you of real-world hardware concerns. If your SDR is getting overloaded because of bad pass-band filtering then no amount of software is going to save you.
