Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
What else can I help you with?
What amplifier circuit is typically used as the input stage for an operational amplifier?
Differential amplifier ANSWER: A differential amplifier is an op amp. If any amplification is required a preamplifier is used mainly to cut the white noise and improve the input impedance
Is paper capacitor use in transistor amplifier?
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
What is the use of finding the bandwidth of an amplifier?
A: Any amplifier will have greater band with if operated open loop. It will also be very unstable so negative feedback is implemented for that reason. There is some drawback when feedback the band width of the amplifier decreases, So is important to find out if the amplifier when stable will it have the band width required
Instrumentation amplifier is used for?
used for measurement and test equipment. its used where great accuracy and stability of circuit are required.
Techniques required for increasing the input impedance?
...of what? to a house, to a breaker (to lower fault current level?), to an amplifier circuit?
How is transformer saturation avoided in class B push pull amplifier operation?
In class B amplifier no DC biasing required, thus lack of of DC current in inpunt and load, saturation of core avoided
Which replacement control knobs are required for a Marshall Amplifier?
Amp Repair Parts, Ali Express and Guitar Nucleus are great guitar stores to check out to find the necessary amplifier part needed for your musical instrument.
Is an alternator upgrade required to intall subwoofers in older cars?
Depends on the size of the amplifier you are installing and the power required to run it. You can easily install a 500 watt amp with no problems.
Does an amplifier violate law of conservation of energy?
NO. THE UNIVERSAL LAW STILL APPLIES -- ENERGY CANNOT BE CREATED NOR DESTROYED -- ONLY TRANSFORMED. Actually in amplifier we give it the Vcc,Vee,Vbb which is such value from which the gain of an amplifier cannot increase till the point of Vcc,it holds the law of conservation of energy but if gain reaches to Vcc then it is in cutoff region so,never the amplification process violate the law of conservation of energy Actually in amplifer we want the required phase shift+amount of required voltage from sources present so this is actually the use of amplifier that it enhances our strength over particular shape waveform and magnitude at required point
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
Why do you use feedback?
The voltage gain,input impedance,output impedance,bandwidth etc. are the characteristics of amplifier's. these are more or less constant for a given amplifier. These parameters are required to be controlled. This can be done by using feedback that's why we use feedback.
Where to find the on-board amplifier in a Lincoln town car?
The amplifier for the sound system is in the trunk on the right hand side of the car attached the the vertical panel on the trunk side of the rear seat. On most sound system options, this amplifier has a pre-amp required for the factory radio. If you are installing an aftermarket radio, you will need a bypass plug to eliminate the on board amplifier yet utilize the existing wiring and speakers.
