Test: Transfer Function - 2 - Electronics and Communication Engineering (ECE) MCQ

The non-minimum phase transfer function is defined as the transfer function which has zeros (or) poles in right side of s-plane.

Type of System: The Type of system denotes the no. of poles at the origin of the open loop transfer function G(s)H(s).

Hence, there is no open loop pole at origin. Hence, type of system = 0.

Order of a System: The order of a control system is determined by the highest power of 's' in the denominator of its transfer function.

Hence, highest power of s of the characteristic equation 1+ G(s) = 0 will be 2.
Hence, order of given System = 2.

For Z < P, 

∴ Here, number of zeros = 1 and no. of poles = 2
∴ P - Z = 1
When s →∞, transfer function becomes zero. Thus, there is one zero (P - Z = 1) at infinity. Thus, assertion is true.
Since value of transfer function becomes zero as s →∞ therefore, reason is false.

Let i be the current in the given circuit.

Superposition theorem states that for two signals additivity and homogeneity property must be satisfied and that is applicable for the LTI systems.

Given differential equation is 

Given, c(t) = 1 + 0.25 e^-50t - 1.25e^-10t


Thus,C(s)/R(s) is in time constant form having steady state gain = 1.

For given network, total input impedance is

From given pole-zero plot, transfer function is 

So, gain factor K =12

The type of a system denotes the no. of poles at the origin of the open loop transfer function G(s)H(s).
