What is offset current?
On a differential amplifier while there is some voltage offset there is also current offset which is dependent on the value of the F/B resistance the bigger value the more offset.
What are the applications of jfet transistor?
The Junction Field Effect Transistor (JFET)exhibits characteristics which often make it more suited to a particular application than the bipolar transistor. Some of these applications are: - High Input Impedance Amplifier - Low-Noise Amplifier - Differential Amplifier - Constant Current Source - Analogue Switch or Gate - Voltage Controlled Resistor
What is the difference between normal amplifier and operational amplifier?
To oversimplify it the "operational amplifier" was originally designed to perform mathematical operations in electronic analog computers. The designer set the mathematical operation of each amplifier by designing its feedback network. Some operations that could be done were: addition, subtraction, constant multiplication/division, logarithm, exponentiation, variable multiplication/division by combining logarithm-addition/subtraction-exponentiation, integration, differentiation, absolute value, clipping, etc.A "normal" amplifier was just designed to produce a certain amount of voltage or current gain.
How do you write protect your power point presentation?
You can write protect your Power Point presentations via some external applications. These are security applications that make it write only.
What is difference between the ic555 and ic741?
The 555 is a timer integrated circuit. The 741 is an operational amplifier (op amp) integrated circuit. Both are some of the most popular 8 pin integrated circuits ever produced.
Why is negative feedback used in high gain amplifier?
A: Well for one thing if it is positive feedback the amplifier will saturate to one one side of the power buss or the other. An operational amplifier open loop gain can be 90Db which a tremendous gain so some negative feedback is necessary to reduce the gain and make the amplifier behave in the linear region for amplification
How does the operational amplifier work?
The operational amplifier is a device with two inputs, and one output. One input is called non-inverting, while the other is called inverting. Sometimes, there are two outputs, in which case one is also non-inverting and the other inverting. Within the limits of the design of the operational amplifier and its circuit, the output will assume whatever state is necessary to make the two inputs equal to each other. The output goes in the same direction as the non-inverting input, or in the opposite direction as the inverting input. Note that for the operational amplifer to work correctly, there needs to be some kind of feedback loop, usually from output to inverting input (we call this negative feedback), so that the output can track one of the two inputs in the ratio of the bridge that is setup in the circuit design.
Is booster used in television cable is amplifier or not?
Yes, a booster is an amplifier. There are several types, some with multiple outputs, some with only one output.
What is a tube guitar amp?
A tube guitar amplifier basically is a large speaker which contains tubes inside the amplifier box for guitar use. Some are vintage and some are classic.
What is the cause of amplifier having garbled sound.?
It may not be the amplifier at all ... it could be that the speaker cone is torn. If it is the amplifier it would mean that some component in the audio output section is faulty and needs repair or replacement.
What is Bandwidth of RF amplifier?
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
Do you connect speakers to receiver or amplifier?
Depends on what your definition of "receiver" is, but most of the time - to the amplifier. Consider: if the receiver is some form of a device that receives some signal, and then decodes it to audio, then the receiver will hook into the amplifier, which in turn will drive the speakers (so the speakers go to the amplifier) if, on the other hand, the receiver is a part of a wireless connection between the amplifier and speaker, then it really serves the role of a cable, so in essence you're again connecting the speakers to an amplifier (only using the receiver as an intermediary) You would have to specify your case.
