I am looking for a formula to calculate the Average Power of a square wave used in APSK Modulation.
In my textbook, the example above is given with no formula so I am a loss how the value for average power (4.5) is calculated in the bottom example.
I assumed from the top example that it was simply the square of the amplitude divided by the ON Time Period, but applying that logic to the bottom example gives a value no where near so I have a feeling some integration may be involved.
Any suggestions would be greatly appreciated.
