E4D10 - Amateur Extra Class

E4D10 : What does a third-order intercept level of 40 dBm mean with respect to receiver performance?
A Signals less than 40 dBm will not generate audible third-order intermodulation products
B The receiver can tolerate signals up to 40 dB above the noise floor without producing third-order intermodulation products
C A pair of 40 dBm input signals will theoretically generate a third-order intermodulation product that has the same output amplitude as either of the input signals
D A pair of 1 mW input signals will produce a third-order intermodulation product that is 40 dB stronger than the input signal
Correct Answer: A pair of 40 dBm input signals will theoretically generate a third-order intermodulation product that has the same output amplitude as either of the input signals
