A carrier signal of (500 kHz) is amplitude modulated to a depth of 75% by a single tone modulating signal of 18 KHz. The carrier amplitude is 800 Volts , and the antenna equivalent impedance is 70 Ohms. Calculate:
1- modulating wave voltage (Am) [volt]
2- The carrier power (Pc) [Watt]
3- The average output Power (Pt) [watt]
4- The percentage transmission efficiency [%]
5- The lower side band power (PLSB)
