Test: Circuit Analysis in the s-Domain - Question 1

What will be the response for the below figure?
The characteristic roots are real & unequal (-1, -3)

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 1

The characteristic roots are real and unequal (-1, -3), therefore it is over damped.

Test: Circuit Analysis in the s-Domain - Question 2

The current response of a network to a unit step input is Io(s) = 10(s + 2)/s(s2 + 11s + 30). The response is

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 2

The roots are real and unequal (-6, -5) for the characteristic equation. Hence it is over damped.

Test: Circuit Analysis in the s-Domain - Question 3

The network function (s2 + 8s +15)/(s2 + 6s + 8) is

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 3

The singularity nearest to origin is a pole. So it may be a RL admittance or RC impedance function.

Test: Circuit Analysis in the s-Domain - Question 4

A valid immittance function is

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 4

a) pole lie on positive real axis
b) poles and zero does not interlace on axis.
c) poles and zero does not interlace on axis.
d) is a valid immittance function.

Test: Circuit Analysis in the s-Domain - Question 5

The network function (s + 1)(s + 4)/s(s + 2)(s + 5) represents

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 5

The singularity nearest to origin is a pole. So it may be RC impedance or RL admittance function.

Test: Circuit Analysis in the s-Domain - Question 6

The network function (s2 + 4s)/(s + 1)(s + 2)(s + 3) represents

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 6

Poles and zero does not interlace on negative real axis so it is not a immittance function.

Test: Circuit Analysis in the s-Domain - Question 7

What is the ratio of the transfer function Io/Is?
The ratio of the transfer function Io/Is is s(s + 4)/(s + 1)(s + 3)

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 7

Io/Is = (s + 4)/ (s + 4 + 3/s) = s(s + 4)/(s + 1)(s + 3).

Test: Circuit Analysis in the s-Domain - Question 8

The voltage response of a network to a unit step input is Vo(s) = 10/s(s2 + 8s + 16). The response is

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 8

The characteristic equation has real and repeated roots (-4, -4). Hence it is critically damped.

Test: Circuit Analysis in the s-Domain - Question 9

The network function s^2 + 10s + 24/s2 + 8s + 15 represents

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 9

The singularity is near to origin is pole. So it may be RC impedance or RL admittance function.

Test: Circuit Analysis in the s-Domain - Question 10

The network function (3s2 + 8s)/(s + 1)(s + 3) represents

Detailed Solution for Test: Circuit Analysis in the s-Domain - Question 10

The singularity nearest to origin is a zero. So it may be RL impedance or RC admittance function. Because of (D) option it is required to check that it is a valid RC admittance function. The poles and zeros interlace along the negative real axis. The residue of Yrc(s)/s is positive.
