What is chopper amplifier?
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
What are Ac load lines in an amplifier and how they are drawn?
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.
What is the emitter bypass capacitor?
The capacitor helps to keep the quiesent point fixed. During its operation it bypasses the ac component. If the ac also flows through this emitter link then as we know by parameter equations emitter current and ce voltage changes hence varying q point.
What is an amplidyne?
An amplidyne is a form of electromechanical amplifier in which an AC motor drives a DC generator.
What is meant by the term large signal amplifier?
power amplifiers are the amplifier which raise the power levels of the signal.the power amplifier may also defined as a device which converts dc power to ac power and whose action is controlled by the ac input signal. Power amplifiers are also known as "LARGE SIGNAL AMPLIFIER".the term large signal arises because they use large part of load line for their operation,but the small signal amplifiers are use only 10% load line for their operation.
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.
Where is the ac amplifier located on 1999 Geo Tracker?
never heard of a ac amplifier
What are the two basic configurations in operational amplifier?
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
What is chopper amplifier?
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What are Ac load lines in an amplifier and how they are drawn?
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.
What type of signal to amplify by using differential amplifier?
ac and dc

What happens if by pass capacitor is not present in the amplifier?
If a bypass capacitor is not present in an amplifier, the gain may be reduced due to increased emitter resistance, which can negatively affect the amplifier's frequency response. This could lead to poor performance, particularly in AC signal amplification, as the capacitor typically helps to stabilize the biasing and improve AC gain by providing a low impedance path for AC signals. Additionally, the absence of the bypass capacitor may result in unwanted feedback and reduced overall efficiency of the amplifier circuit.
You want to connect car sub woofer amplifier to AC 220 volts by using a step down transformer What should be the output ampere for the transformer so that you can use the car sub whoofer amp with AC?
About 1A To 1.5A (or 2A) i tested it one month ago.
