Author: Radoje Jankovic.

Test question #1.
Q.
A two – port network is a network which has two input and two output terminals.

A. Yes or No.

Test question #2.
Q.
A two – port network, may also be called a four – terminal network or quadripole network.

A. No or Yes.

Test question #3.
Q. 
The ABCD parameters or constants are sometimes called the linear parameters or auxiliary constants of the network.

A. Yes or No.

Test question #4.
Q.
The constant A and D of the linear parameters are dimensionless constants, and B is a constant with the dimensions of an impedance, and C is a constant with the dimensions of a admittance.

A. True or False.

Test question #5.
Q.
In a linear two – port network, there will be a linear relationship between input voltage and current (V1, I1), and output voltage and current (V2, I2).

A. Yes or No.

Test question #6.
Q.
For a symmetrical network,
Z 1in = Z 2in 
and
A = D

A. Yes or No.

Note: All quantities are in the complex form.

Test question #7.
Q.
For a passive electrical network is:

AD – BC = 1

A. True or False.

Att. All are complex numbers.

Test question #8.
Q. 
An artificial delay line may be constructed of a ladder network of series connected inductors and shunt capacitors. This network has the characteristic of delaying a signal which is applied to it.

A. True or False.

Test question #9.
Q.
The linear parameters ABCD of a two – port network can bie expressed in per-unit values.

A. No or Yes.

Test question #10.
Q.
Non-complex A.C. waveforms are often referred as complex waves.

Test question #12.
Q.
The total power factor of a single-phase network when harmonics are present is defined as:

PF = Total power/(V x I)

True or False.

Test question #13.

Q.
In power – frequency networks, calculations are usually made in terms of r.m.s values, and these true r.ms. values are measured by analog or digital instruments i.e. with moving – iron or electrodynamic instruments.
