1. A power (Pv)dBm = −16 dBm is measured across a resistive load  for the signal  with frequency f0 = 500 Hz. Express the signal amplitude V0 in V and dBm, where
2. Let the source PSD of a two-terminal device, closed on a load, be
With  Knowing that the source impedance is ZS = 100 + j50 and that the system is matched, what is the average power Pv and the power density pv(f ) at the load?
