What is the Q factor in RLC circuit?
It is related to damping in the circuit using a resistor. Q is inversely proportional to the resistor(R). So if the value of resistance is high, there is a greater damping and the value of Q will be low. if resistance is low, there is small damping and Q will be high. when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large. Go do some research on the graphs and the formula of Q factor to understand it better.
Why negative feedback amplifier is preferred to positive feedback amplifier?
The negative feedback tends to stabilize the circuit; positive feedback would make it more unstable. For example, the "beta" of a transistor OF THE SAME SERIES - this is basically the amplification factor - may vary between 100 and 1000. With negative feedback, the circuit is hardly affected by these changes in beta - at the cost of a reduced amplification.
What is a Scaling amplifier?
3-63A SCALING AMPLIFIER is a special type of summing amplifier with the output signaldetermined by multiplying each input signal by a different factor (determined by the ratio of the input-signal resistor and feedback resistor) and then adding these products
What is that 1.414 value used in electronic circuits?
1.414 is the approximate value of the square root of 2. The ratio of 1.414 is useful in many different places. Two examples are the conversion from RMS value to peak value for a sinusoidal save form, and the calculation of power factor when the phase angle is 45 degrees.
What is the reciprocal of the power factor?
impedance/resistance

What is The damping factor of an active filter?
good things
What is the definition of feedback factor?
the feedback factor is when you give something and get positive or negative feedback but in order t get this you have to lay something an (idea) to get "the feedback factor.
What is definition of feedback factor?
The ratio of Feedback voltage and output voltage.

What is Impedance ratio?
Transformer Z-ratio = (Zpri / Zsec) = (Vpri / Vsec)2 It could also be the damping factor DF = Zload / Zsource The damping factor DF is the load impedance Zload (input impedance) divided by the the source impedance Zsource (output impedance).
what direction does negative feedback mechanism drive the factor being regulated?
in the oppesite direction ;)
What is the expression for sensitivity factor in negative feedback amplifier?
[1/(1+Ab)] is the expression for sensitivity...

What system is responsible for maintaining homeostasis via electrical signals?
the maintenance of homeostasis by the factor of feedback machenism..
Describe why a thermostat is an example of a feedback loop?
because a change in one factor (the temperature) causes a response that brings that factor back to normal. example. control center
