7. The specification for a receiver states that its minimum sensitivity is 0.2 µV RMS (i.e., the receiver must see an RF signal of at least this magnitude in order to demodulate the signal properly). If the receiver's RF input (or "front end") impedance is 50 №, what is the power developed by a 0.2 µV signal, in dBm?
