What needs to be considered to ensure successful communications over guided or unguided mediums?

Select the correct statement(s) regarding packet switching.

When a transmitted signal encounters an object with a relatively sharp edge, it will appear to change propagation direction.  This is called:

Delay distortion occurs when the frequency components of a transmitted signal arrive out-of-phase from one another. While this is a problem for digital communication systems, it is simply an annoyance for analog systems.

Repeaters are often used on both analog and digital communication systems to eliminate noise.

Determine the decibel value of SNR given a signal power, S=-100dBm, and noise power, N=-133dBW.

Which of the following determine the capacity of data in bits per second that can be supported over a transmission medium?

Given a receive power of 8E-6 mW and a noise power in decibels of N= 144E-13 W, determine the decibel SNR value.

Select the correct statement(s) regarding periodic, aperiodic signals and frequency bandwidth.

Multipath fading in an urban environment is a severe issue for unguided digital communications.  Because of this, MIMO (multiple in, multiple out) antenna systems should never be used for communications in an urban setting.
