My question is: What happens when two modulated rf signals encounter a nonlinear circuit causing the two signals to be mixed (Heterodyning). Say the signals are BOTH 100 KHz. one modulated by a steady 500 Hz signal the other modulated by a 900 Hz.
Would you get back a 400 Hz signal or multple there of? (400,800,1200.1600 etc) (1400 Hz and multiples of 1400 Hz) OR
Would you get nothing with the 100 KHz carrier signals canceling each other out?
Now! what would happen if you left the modulation at 500 Hz and 900 Hz and changed one of the carrier signals to, say 100.020 KHz? (20 Hz higher than the other.)
What would you get back? 20 HZ or what? Modulation???
What would happen to the modulation signals?
