Talk:RF front end

digital
The last paragraph seems to not make it obvious that sampling is done at IF, at least for the multi-GHz (WiFi and cell phone) signals mentioned. I suppose for lower frequencies (AM and FM radio) mixing could, and probably should, be done with DSP, though I don't know that this is common yet. Gah4 (talk) 10:58, 27 January 2019 (UTC)
