A: Amplify DC a1 volt can be amplify to 10volts for example if need be
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
It is called an amplifier.
Amplifier repeater
A class "A" amplifier amplifies the entire waveform, a class "B" amplifier only amplifies the first 1/2 of the wave form. See the images in the related link.
An amplifier amplifies the small input signal to a high signal without changing its freqency.
Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
It "amplifies" the signal of your stereo so it is louder to hear.
it amplifies both the incomeing and outgoing signals on CB radios
A repeater that does not distinguish between noise and signal; it amplifies both.
A repeater that does not distinguish between noise and signal; it amplifies both.
A: DC couple amplifiers refers to stages of amplifiers where is the biasing is direct without adding capacitors to remove the DC component from amplifier to amplifier
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.
