What are the application of voltage shunt amplifier?
Applications of Voltage shunt feedback amplifier?
Difference between amplifier and feedback amplifier?
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.
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 are the differences of Long shunt vs short shunt generator?
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
Explain current shunt negative feedback amplifier?
describe current-shunt negative feedback as applied to operational amplifiers, including derivations of the gain relation for each type of negative feedback.

What is difference between series fed and shunt fed hartley oscillator?
The DC voltage for the amplifier (transistor or FET) runs for a series-fed oscillator through the inductance of the LC circuit. A shunt-fed oscillator uses a radio-frequency choke or a resistor to deliver DC voltage to the amplifier. For an oscillator the difference between serial-fed and shunt-fed is small. The choke resonance frequency can interact with the LC circuit resonance frequency. This problem happens only with shunt-fed. Furthermore series-fed needs less components. Therefore it is prefered for (low power) oscillators. The output circuit of an amp can be series-fed or shunt-fed, too. The additional DC current through the coil will drive a iron or ferrite core earlier into saturation. This is an disadvantage of serial-fed. At a high-voltage tube RF amp with say 2000V DC voltage, in the shunt-fed amp only the choke and the DC blocking capacity have to withstand the high voltage. This is an advantage of the shunt-fed solution.
What are the differences of Long shunt vs short shunt generator?
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
What is amplifier roll off?
A practical amplifier will contain several components of a "shunt" capacitance inherent in the transistor and physical wiring of the amplifier circuit. As the frequency of the input signal increases, the reactance of these shunt-capacitances will decrease until, at a frequency determined by the value of the shunt-capacitance and the circuit impedance, signal attenuation begins to take place. Thus the shunt capacitances limit the high-frequency response of the amplifier (note that the transistor itself also has inherent limits to it's high frequency amplifying capability). In the case of operational amplifiers, many operational amplifiers are internally compensated by a small capacitor (e.g. about 30pf for a 741). The internal frequency compensation capacitor prevents the operational amplifier from oscillating with resistive feedback.
What is the difference between shunt and series regulator?
Basic voltage regulators are classified as either SERIES or SHUNT, depending on the location or position of the regulating element(s) in relation to the circuit load resistance.
Why you use 250 Ohm resistor in series with HART protocol communication?
You need to use the 250 Ohm resistor in series with HART protocol communication because it acts as a shunt resistor.
