Suggestions:

Comprehensive topic: Include....

Math. Circuits - basic typicals. Engineering considerations: Look into ... the complexities of designing signal amplification circuits vs antenna design (mobile phones) --sub topic antenna design .... reciprocating functions, Genetic algorithms, etc.

Is there a limit to the signal boosting? LED light and laser diodes can be boosted with a higher electric current, and with too much they burn out. Does this happen with preamps? The higher the current, the most interference noise, but not all radio signals are sending audio.-- Wyn.junior ( talk) 23:09, 13 March 2014 (UTC) reply
