selection of operating point is very important in the electronics circuit designing or construction of amplifiers
1. operating point is generally selected as the point of intersection of both DC and AC load lines.
2. they may also be chosen as the mid-point of DC load line if maximum symmetrical swing of the signal is desired
What else can I help you with?
What is operating point instability and need of stabilization?
A: And system or amplifier may have instability as some point due to external or internal function therefore intervention is needed to stabilize the system at that particular point of operation.
Why we kept VOLTAGE collector to emitter half of voltage vcc?
We bias the common emitter amplifier to have a collector-emitter voltage of one half of Vcc in order to set the operating point halfway between the two extremes.
How operating point of transistor shifting?
Usually, the operating point of a transistor shift because of temperature induced gain or bias changes.
What is an unbiased transistor?
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
What are Ac load lines in an amplifier and how they are drawn?
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.
Quiescent operating point of a transistor amplifier lies in?
It lies in middle of the DC load line of that Amplifier.
What is the operating point in transistor biasing?
The operating point of a transistor is the point on its conduction curve that the engineer has selected for its operation, based on the intended function of the circuit the transistor is used in. This will vary with this function:a class A amplifier will have its operating point in the center of the linear range of the conduction curve.a class B amplifier will have its operating point at the cut off point of the conduction curve.logic gates will usually have the operating point near the cut off point off the conduction curve.etc.
Aim of load line analysis of a transistor amplifier?
to achieve quiecent operating point
Why you are giving dc supply for biasing the amplifier why not ac?
The purpose of biasing an amplifier is to shift its operating point, so that when you apply a signal in you will get a expected signal out. The operating point is generally in the middle of the linear region. You would not use AC for the bias, as that would cause the operating point to constantly shift, and you would then not be able to differentiate between the signal and the bias.
What are operating point int transistor biasing?
A: An operating in biasing is determined by the transistor capabilities as a linear amplifier. Basically it is a bias to insure linear operation with the loading of the output
What is operating point instability and need of stabilization?
A: And system or amplifier may have instability as some point due to external or internal function therefore intervention is needed to stabilize the system at that particular point of operation.
What is the need of bias in circuit?
To severely oversimplify it: to set the operating pointof the circuit.In more detail, amplifying devices like vacuum tubes and transistors are inherently nonlinear and only amplify over a limited range of voltages and currents. An operating pointmust be selected on the device's response curve and then bias set in the circuit to maintain the device at that operating point to make the circuit do what is desired.for an amplifier with good linearity (class A) the selected operating point is in the middle of the most linear part of the curvefor a high power amplifier (class B push-pull) the selected operating point is at cutoff, with one device amplifying while the other rests then on the next half cycle they switchfor digital circuits the selected operating point is usually well beyond cutoff and gain is set very high so as soon as the device is driven out of cutoff by a signal it saturatesetc.
Why we kept VOLTAGE collector to emitter half of voltage vcc?
We bias the common emitter amplifier to have a collector-emitter voltage of one half of Vcc in order to set the operating point halfway between the two extremes.
What are the least efficient of class of amplifier?
class b amplifiers as for class b amplifier the 'Q' point is near to cut of region.
In select circumstances is a permissible character on the Mac operating system.?

Is it possible to download an operating manual for a line6 spider11 guitar amplifier?
Yes, you can download them from Line6 website for free
Can a car amplifier make any music sound better?
The point of a car amplifier is the make music sound better, so in most cases all amplifier make music sound better.
