QUESTION :When two transmitters operate on the same frequency in close proximity to each other, cochannel interference can occur.

True False

QUESTION : Crosstalk noise can occur in either guided or unguided communication channels.

True False

QUESTION:Coaxial conductors use unbalanced signals, which means that it is less capable than UTP balanced conductors with regards to data rate capacity and attenuation.

True False

QUESTION :The beam width of a signal transmitted from a directional antenna will decrease as the transmission frequency increases.

True False

QUESTION :Link margin is the difference in decibels between the actual power received, and the receivers specified receiver sensitivity.

True False

QUESTION :When microwave communication systems are used, it is important to ensure line-of-site (LOS) throughout the Fresnel zone.

True False

QUESTION:Polarization of an electromagnetic wave (EM) is determined by the polarization of the electrical field (i.e., not the magnetic field)

True False

QUESTION The Antenna Reciprocity Theorem states an antennas electromagnetic properties will be the same whether it is transmitting or receiving.

True False

QUESTION Depolarization of a transmitted signal reduces the amount of energy transfer between the RF wave and antenna.

True False

QUESTION: An unguided signal can be split into several transmission paths, with each path experiencing different impediments (e.g., reflection, scattering, etc.), thus causing each path to vary in length. This results in several copies of the signal reaching the receive at slightly different times, thus leading to signal distortion. This is termed multipath fading.

True False

QUESTION: MIMO antenna systems intentionally takes advantage of multipath using spatially diversified transmit and receive antennas, and digital signal processors (DSPs).

True False
