Calculate the power gain in decibels for each of the following cases.
a. Po = 100 W, Pi = 5 W.
b. Po = 100 mW, Pi = 5 mW.
c. Po = 100 mW, Pi = 20 μW.
Determine GdBm for an output power level of 25 W.
Two voltage measurements made across the same resistance are V1 = 110 V and V2 = 220 V.
Calculate the power gain in decibels of the second reading over the first reading.
