Question

A broadcast radio transmitter radiates 10kw when the modulation percentage is 60. Calculate its carrier power.

Answer 1

Please let me know if you have any problem

Answer 2

Answer:8.475KW

Explanation:

Percentage of modulation is 60% i.e.  m=0.6

Transmitted power   Pt=10 kW

Thus unmodulated carrier wave   Pc=  Pt/{1+(m^2)/2}

therefore Pc= 10[/1+(0.6^2)/2}
=8.475KW
