Input impedance of current shunt feedback amplifier?
The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)
What is the difference between normal amplifier and magnetic amplifier?
normal amplifier is a mathametical operation analog the computer, magnetic amplifier is sound operation of the signal
What are the Difference Between AF Amplifier and RF Amplifier?
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
What are the application of voltage shunt amplifier?
Applications of Voltage shunt feedback amplifier?
Can we use positive feedback in amplifiers?
Yes because an amplifier with positive feedback is an oscillator.
Types of Negative feedback amplifier?
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
What is the difference between feedback and control?
difference between feedback and control
What is the difference between voltage series and current series amplifier?
The main Difference between Voltage and Current Feedback Amplifiers is in the sampled(Output) signals. In Voltage feedback the sampled signal is voltage (Vf=Beta*Vo) where Vo is the sampled signal and for current feedback it is current signal (Vf=Beta*Io).
Reason use an op amp in a closed loop control system?
Differential Amplifier or Summing Amplifier are usually used in a closed loop control system. The error signal will be the DIFFERENCE between the setpoint value and feedback value for Differential Amplifier. Whereas for Summing Amplifier, the error signal will be the difference between the setpoint value and feedback value only if one of the value is inverted in polarity. Another reason Op Amp is used: amplify the error signal as error signals are usually very small. Hope this helps.
What is feedback amplifer?
A negative feedback amplifier (or more commonly known as feedback amplifier)can be defined as an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.
In a feedback amplifier positive feedback produces an output that is?
In a feedback amplifier, positive feedback produces an output that is in-phase with the input signal. This can lead to instability and oscillation in the amplifier circuit. Positive feedback can increase the gain but at the risk of introducing noise and distortion.
Difference between oscillator and amplifier?
The amplifier projects the audio signal into something we can comprehend. The oscillator creates a fixed or variable pitch, which is fed to the amplifier. Amplifiers are circuits which transfer an input signal into an output signal. Oscillators are autonomous circuits powered by a constant energy source. They produce a steady state signal e.g. a sinusoidal signal or a chaotic signal.
What is the application of feedback amplifier?
A: feedback is not an application but rather is a must to keep a system or amplifier stable in the linear regions
Is an amplifier a negative feedback?
Yes, Amplifire have negative feedback.
What is the effect of negative feedback in a noninverting amplifier?
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
Input impedance of current shunt feedback amplifier?
The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)
