Hello,


To calculate the total power in the AM wave and power in each sideband, we can use the following formulas:


1. Total Power (Pt) = Carrier Power (Pc) x [1 + (μ^2)/2]


where μ is the modulation index (80% in this case)


1. Power in each sideband (Ps) = (μ^2/4) x Pc


Given:

Pc = 500 W (carrier power)

μ = 0.8 (modulation index)


Calculations:


1. Total Power (Pt) = 500 x [1 + (0.8^2)/2]

= 500 x [1 + 0.64/2]

= 500 x 1.32

= 660 W


2. Power in each sideband (Ps) = (0.8^2/4) x 500

= (0.64/4) x 500

= 0.16 x 500

= 80 W


So, the total power in the AM wave is 660 W, and the power in each sideband is 80 W.

Hope this helps,

Thank you
