If an inline capacitor is inserted in the feedback from the output to the input of an op-amp it will act as a frequency filter and only boost audio frequencies within the resonant frequency range of the capacitor. If you gang multiple op-amps in a wein bridge arrangement you get an analogue audio filter capable of shelf boost or cut.

What is an electronic device that can serve as a gate or switch for an electrical signal and can amplify the flow of electricity?
transitor
What is active devices?
An active device amplifies the signal by some value - such as an active filter using an OPAMP. A passive device does not provide any amplification - such as a passive filter network of inductors and capacitors.
IC 741 is an?
It is an opamp chip consisting of 8 pins
Working principle of cathode ray oscilloscope?
A scope is nothing else then a display instrument it will amplify and display a signal on a CRT for visual analysis
How do you amplify a square signal?
To easily do that all you need is a higher voltage level or the level that you desire . square waves usually are states of [1] or rail voltage and on[0] saturation voltage. to linearly amplify these square waves you will need a hi band pass amplifier . Possibly 50megahz or so
Which of following OP amp is used to strengthen the week signal?
741 opamp
Why amplifier is required?
Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
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 the verb for amplify?
Amplify is a verb. This device amplifies the signal from the microphone so that it can be heard.
What are advantages and disadvantages of multistage amplifier?
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
What is the applications opamp buffer circuit?
An opamp buffer circuit is one where the input signal is connected to the plus input, and the output is connected to the minus input. Within the performance limitations of the opamp, the output will track the input. The advantage of the buffer circuit is that is presents very little load impedance to the input signal, while providing a low impedance from the output to drive whatever circuitry is connected there.
How is phosphorylation important in a signal transduction cascade?
Phosphorylation will turn an inactive protein into an active one, which triggers another response in the cell.
Why you add a positive voltage to the ac signal to allow a transistor to amplify ac signal?
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
What is the principle of positioner in control valve?
to amplify the input pneumatic signal
What are transistors used in a mobile phone?
they amplify the phone's incoming signal
What type of signal to amplify by using differential amplifier?
ac and dc
What is the difference between signal processing and signal conditioning?
processing is nothing
