A typical method of measuring the linearity of an amplifier is called the "Two-tone" test. Signals at f1 and f2 are input to the amplifier and the output spectrum is observed. Assuming that signals at 14.1 and 14.2 MHz are input to an amplifier, with both signals at an input power of -10 dBm, (1) at what frequency or frequencies would you look for signals that are caused by 3rd order intermodulation distortion? (2) If you found a signal at one of these frequencies with a signal power of -60 dBm, what would you expect the signal level to be when the f1 and f2 signals were changed to a power level of -5 dBm?
