It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.

What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier signal.
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
What is selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.

What is carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
What component of an AM transmitter generates the carrier frequency?
The classic AM transmitter layout is a master oscillator, followed by a "pen", or penultimate amplifier, followed by a PA or power amplifier. The master oscillator, which is probably crystal controlled, generates the carrier frequency.
What is the definition of master oscillator?
An oscillator that establishes the carrier frequency of the output of an amplifier or transmitter.Source : Answers.com

How does power amplifier differ from a conventional voltage amplifier?
A voltage amplifier does not have to supply significant current bur a power amplifier does.
Were do you buy a voltage amplifier?
In audio look at an amplifier. It will be always a voltage amplifier.
