An intelligence signal is amplified by a 65% efficient amplifier before being combined with a 250W carrier to generate an AM signal. If it is desired to operate at 50% modulation, what must be the dc input power to the final intelligence signal amplifier

"192.3 watt" is the right answer.

Explanation:

Given:

Efficient amplifier,

= 65%

or,

= 0.65

Power,

As we know,

⇒

By putting the values, we get

Now,

⇒

DC input (0.65) will be equal to "".

hence,

The DC input power will be:

=

=

=

explanation:

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
