Why amplifier is called amplifier?
The root word "ample" means abundant, having lots of something, as in, we had ample food to eat at the feast. To amplify means to make something more ample. So when it comes to sounds, if you take a faint sound and make it louder, you are amplifying it. That is what an amplifier does.
What does a comparator do in electronics?
A comparator is an operational amplifier used without a feedback circuit. The output of the comparator will be high when the voltage of the non-inverting input is below the inverting input, and low when the inverting is above the non-inverting input. The output is undefined - i.e. can by anything - when the voltages are equal.
Why do you need chopper amplifier?
it is used to avoid drift problem
When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
Will analog boster work on didital TV?
I think you mean a (TV antenna amplifier) RF amplifier used with coax cable. The answer is YES it will work with DTV.
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.
How an operational amplifier can amplify DC signals?
It takes the difference between of two input and amplify by the open loop gain of the amplifier or closed loop gain of the amplifier. It is very hard to control open loop gain of 100 Db so it very seldom used
Can inductor be used in 'operational amplifier as integrator'?
let us try.........
What is the amplifier?
An amplifier is an electronic device used to increase the amplitude of electrical signals in sound production.
What is an instrumentation amplifier used for?
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
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
What is video amplifier?
It is a normal amplifier, fast enough to amplify high frequency video signals. The word "video" means wideband. That's why a video amplifier is used for, for instance, for t.v. signals and in wideband measuring equipment.
What are the industrial applications of integrator and differentiator circuits using operational amplifier?
differentiator is used in t.v.
What is ment by amplifier?
The official definition of the word amplifier is "an electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction."
Why do you need small signal amplifier?
Small signal amplifier is needed because it is used for amplifying input signals having low frequency or amplitude.
Why 741 number is used in opamp741?
741 is pin no of operational amplifier that's why the no 741 has been given to opamp741
What is the use of superdiode?
superdiode consist of diode and amplifier circuit.it is used for the rectification of small signals
