Question E4D10

From subelement E4 - E4D

E4D10
Answer: C

What does a third-order intercept level of 40 dBm mean with respect to receiver performance?

ASignals less than 40 dBm will not generate audible third-order intermodulation products
BThe receiver can tolerate signals up to 40 dB above the noise floor without producing third-order intermodulation products
CA 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
DA pair of 1 mW input signals will produce a third-order intermodulation product that is 40 dB stronger than the input signal
