Test: Network Synthesis

QUESTION: 1

Which of the following is a positive real function?

A.
B.
C.
D.

Solution:

Hence, notaPRF.

has a zero (s = 1) in RH s-plane.

Hence, not a PRF.

has a pole and a zero in RH s-piane.
Hence, not a PRF.
Option (b) is a PRF as all poles and zeros lie in LH s-plane.

QUESTION: 2

A network function can be completely specified by:

A.
Real parts of poles
B.
Poles and zeros
C.
Real parts of zeros
D.
Poles, zeros and a scalar factor

Solution:

QUESTION: 3

Which of the following property does not relates to LC impedance or admittance functions?

A.
There must be either a pole or a zero at infinity or origin.
B.
This is the ratio of even to odd or odd to even polynomial.
C.
Poles and zeros lie on negative real axis and they alternate.
D.
The highest or lowest powers of numerator or denominator polynomials differ by unity.

Solution:

QUESTION: 4

If the impulse response is realisable by delaying it appropriately and is bounded for bounded excitation, then the system is said to be

A.
causal but unstable
B.
non-causal but stable
C.
causal and stable
D.
non-causal and unstable

Solution:

Since system is bounded for bounded excitation therefore, it will be stable.
Since the system is delayed therefore, output may exist before the input is applied.
Hence, the system will be non-causal.

QUESTION: 5

A network-A has zeros only in the left-half of the s-plane while the network-B has zeros only in the right-half of the s-plane. The network-A and Network-B will be respectively called

A.
a stable function and an unstable function.
B.
a non-minimum phase function and an unstable function.
C.
an all pass function and a non-minimum phase function.
D.
a minimum phase function and a nonminimum phase function.

Solution:

QUESTION: 6

An L-C admittance or impedance function

A.
has no pole or zero at the origin or infinity.
B.
is an odd rational function.
C.
has simple poles and zeros in the left half of the s-plane.
D.
has all zeros on the negative real axis of the s-plane.

Solution:

QUESTION: 7

If F₁(s) and F₂(s) are positive real functions, then which of the following are positive real function?

A.
B.
C.
Both (a) and (b)
D.
Neither (a) nor (b)

Solution:

QUESTION: 8

For the pole-zero plot shown below, the network function is

A.
B.
C.
D.

Solution:

Here, zeros are at: s = 0, 0,-3

Poles are at s = - 1,

or, poles are at (s + 2)² + 1 - 0 and at s = -1 or, s² + 4s + 5 = 0 and at s = -1

QUESTION: 9

A stable system must have

A.
zero or negative real part for poles and zeros.
B.
atleast one pole or zero lying in the right- half s-plane.
C.
positive real part for any pole or zero.
D.
negative real part for all poles and zero.

Solution:

QUESTION: 10

Which of the following is not a positive real function?

A.
F(s) = Ls(L= Inductance)
B.
F(s) = K/ s ( K = Constant)
C.
F(s) = Rs(R= Resistance)
D.

Solution:

Here, a = 1 , b = 0, c = 2

Thus, a, b, c ≥ 0 but b < a

For PRF, b ≥ a therefore, option (d) is not a PRF.
