These are values which make the denominator equal zero, therefore the system described by the transfer function would be unstable near these values.

What is the meaning of poles and zeros?
poles are the plot of the transfer function of a system on the left side of the origin, in s-plane. zeroes are the right side plot. poles and zeroes specifies the absolute stability of the system.. they also gives the observability and controllability of the system..
Explain open-loop transfer function of a close system?
An open loop transfer function is the transfer function of a system without incorporating the feedback component. For example, where the closed loop transfer function with unity feedback H(s) = G(s)/(1+G(s)) it can be deduced that the open loop transfer function is Y(s)/U(s) = G(s).
Why is the number of poles of stator and rotor same in induction machine?
The number of poles on stator and rotor is always the same. If they are not equal?æno torque will be produced, thus, the machine will not function.?æ
What is the difference between driving point function and transfer fuction?
consider a two port network. if u take the ratio of output of one port either current or voltage/ input of other port either voltage or current, if it is same parameter ie. V2/V1 then we call it as transfer function or gain also. V1 is the input port voltage and V2 is the output port voltage. In s domain also we can call it as transfer function, and also not necessary restricted to s-domain only. Suppose if is of different parameter ie. I1/V2 we can call it as reverse transfer admittance function but thing is to note the presence of 'transfer' term. At the same time the ratio of parameter current or voltage of the same port we call it as driving point function. It can be Admittance function ie. I1/V1 or Impedance function ie. V1/I1
Poles and zeros of a driving point function of a network are simple and interlace on the jw axis The network consists of which elements?
L and C

What is meant by dominant pole in control systems?
The slowest poles of a system (those closest to the imaginary axis in the s-plane) give rise to the longest lasting terms in the transient response of the system. if a pole or set of poles are very slow compared to others in the transfer function, then they may dominate the transient response. If we plot the transient response of the system without accounting for the transient response of the fastest poles, we may find little difference from the transient response of the original system.
What is the difference between transfer function and frequency transfer function?
frequency transfer function deals with transfer in frequency domain, transfer function alone can be referring to any type of transfer in different domain e.g time domain
What is the dominant function of stratified epithelium?
The dominant function of stratified epithelium is to protect underlying structures from mechanical wear and tear.
What is a dominant from of an alleles?
The dominant form is usually the unmutated wild type that still has a function. The recessive is generally the mutated gene and typically corresponds to loss of function of the gene.

What is feed forward transfer function?
product of all transfer function relating input and output when the feedback loop is disconnected from the comparator
What are advantages and disadvantages of transfer functions approach?
advantages and disadvantages of transfer function?
What is the Clipping circuit transfer function?
Transfer function is the relationship between output and input of a circuit. In the clipping circuit, the general transfer function is such that the transfer curve Av is less than 1 for passive limiter and greater than 0 to limit the maximum and minimum voltage value.
When winds generally flow away from the equator and towards the poles what transfer of wind does this cause?
an energy transfer, with heat energy moving away from the equator
Heat from the equator region moved toward the poles in what process of thermal energy transfer?
Convection
What are the types of system stability analysis?
We can classify the systems based on stability as follows. Absolutely stable system Conditionally stable system Marginally stable system Absolutely Stable System If the system is stable for all the range of system component values, then it is known as the absolutely stable system. The open loop control system is absolutely stable if all the poles of the open loop transfer function present in left half of āsā plane. Similarly, the closed loop control system is absolutely stable if all the poles of the closed loop transfer function present in the left half of the āsā plane. Conditionally Stable System If the system is stable for a certain range of system component values, then it is known as conditionally stable system. Marginally Stable System If the system is stable by producing an output signal with constant amplitude and constant frequency of oscillations for bounded input, then it is known as marginally stable system. The open loop control system is marginally stable if any two poles of the open loop transfer function is present on the imaginary axis. Similarly, the closed loop control system is marginally stable if any two poles of the closed loop transfer function is present on the imaginary axis.
