Exam 3: Radio Frequency Communications

What are three advantages of CDMA over TDMA?

A disadvantage of CDMA is that it can only carry one third the amount of data of TDMA.

Which of the following is NOT a common component of all radio systems?

Which type of standard is an official standard controlled by and organization or body open to everyone?

A __________________ filter sets a range of frequencies that include a minimum and maximum threshold.

If a low-pass filter is set at 2200 MHz, which of the following signals would be allowed to pass through?

MATCHING -stray oscillations that result from the process of modulating a wave and that fall outside the range of frequencies used for transmission

MATCHING -transmissions in which data flows in either direction simultaneously

_______________ transmission uses low-power, precisely timed pulses of energy that operate in the same frequency spectrum as low-end noise and is used in WiGig.

Which international standards organization coordinates global communications networks and services and is actually a treaty organization?

What kind of signals can result from the process of modulating a signal with data to be transmitted?

Which multiple access method overcomes the problem of crosstalk and divides the transmission time into several slots?

Which standards organization functions as a clearinghouse for many types of standards development in the U.S.?

Which of the following would take a transmission band of 1000 Hz and divide it into 100 channels of 10 Hz each to accommodate multiple access?

MATCHING -the measure of signal strength relative to the background noise

What type of transmission is a broadcast radio station an example of?

MATCHING -moving a signal from one wire or frequency to another

What does a filter do and why is one needed in a radio system?

Which type of switching is used in a POTS system?

MATCHING -transmission that occurs in both directions but only one way at a time
