Home work?

Tuned circuits are those that use the active components like
Transistors,board layout and such, capacitance to be included in the
over all capacitance of which is in the tuned circuits around it.
Inductance of these same components also play a role in the over all
tuned circuit.

With out this marriage of equality, you wouldn't see the high freq
circuits that's been out for decades.

Draw back is, there is normally a limited range of pass band per
tuned circuit.

Now, go on the net of open your books to get what you need for your
home work.

Its typical to find this kind of questioners on Sunday!.

And "EVERY THING ABOUT THEM" .
That's a lot of info jekob. You have 'till the 4th, get crackin'.

"Everything about them" is too ambitious a question. One could
write a long chapter or even a whole book about tuned amplifiers.

Basically, a tuned amplifier is one that is designed to amplify
only signals within a selected band of frequencies. For example,
you may want to amplify voltages or currents between 0.99 and
1.01MHz. Such an amplifier will generally be tuned to a center
frequency of 1MHz and designed to pass +/- 0.01 MHz on either
side of the center frequency.

The classic technique for tuning uses an inductor (coil) and a
capacitor, but there's also a variety of other techniques. In
practice, the tuned circuit will also pass frequencies outside
the specified range, but to a much less degree.

Your questions present too broad a front and it's not realistic
to expect details other than basic concepts unless you ask more
specific questions.

Ok. Say you amplify the tune "Twinkle Twinkle Little Star".
You get, depending on how well you construct the amplifier,
"Blaze Blaze Super Nova".

Understanding tuned amplifiers is even harder than finding your caps lock
key.
