1.	What Is The Effect On The Transmitted Power Of Am Signal When The Modulation Index Changes From 0.8 To 1?
Answer» The total POWER in an AM is given by PT = PC (1 + m2/2) Where Pc is the CARRIER power and m is the MODULATION index. Therefore, Pt1 = Pc (1 + 0.82/2) = 1.32 Pc Pt2 = Pc ( 1 + 12/2) = 1.5 Pc Increase in power = (1.5 Pc - 1.32 Pc)/ 1.32 Pc = 0.1364 The total power in an AM is given by Pt = Pc (1 + m2/2) Where Pc is the carrier power and m is the modulation index. Therefore, Pt1 = Pc (1 + 0.82/2) = 1.32 Pc Pt2 = Pc ( 1 + 12/2) = 1.5 Pc Increase in power = (1.5 Pc - 1.32 Pc)/ 1.32 Pc = 0.1364

What Is The Effect On The Transmitted Power Of Am Signal When The Modulation Index Changes From 0.8 To 1?

Answer»

The total POWER in an AM is given by

PT = PC (1 + m2/2)

Where Pc is the CARRIER power and m is the MODULATION index.

Therefore,

Pt1 = Pc (1 + 0.82/2) = 1.32 Pc
Pt2 = Pc ( 1 + 12/2) = 1.5 Pc
Increase in power = (1.5 Pc - 1.32 Pc)/ 1.32 Pc
= 0.1364

The total power in an AM is given by

Pt = Pc (1 + m2/2)

Where Pc is the carrier power and m is the modulation index.

Therefore,

Pt1 = Pc (1 + 0.82/2) = 1.32 Pc
Pt2 = Pc ( 1 + 12/2) = 1.5 Pc
Increase in power = (1.5 Pc - 1.32 Pc)/ 1.32 Pc
= 0.1364
