week 4 pt 3 Flashcards
True or False: Analog is discrete, digital is continuous
False
What is amplitude
Wave’s strength (max/min)
Frequency
Number of cycles over a fixed time period (Hz)
Wavelength
Distance between cycles, Inversely proportional to Frequency
Phase
Wave’s change over time in relation to a fixed point
Channel
Distinct communication path between nodes
Throughput
Measures amount of data transmitted in bits per second
Bandwidth
Capacity that data can be transmitted measured in Hz
True or False: Amplifier distorts analog signal by noise and Repeater distorts digital signal
True
Latency
Delay between signal transmission and receipt caused by cable length
Jitter
Variation in latency
RTT (Round trip attenuation)
Time for packet to go from sender to receiver then back
Attenuation
Loss of signal in dB
What is attenuation caused by
Range, interference and wire size
