cs578 midterm ch1 questions & answers
when was the first wave and who invented the wireless telegraph ch1 -
answer The First wave was in 1896 and by Marconi(wireless telegraph)
when signal sent across Atlantic Ocean from Cornwall, England to
Newfoundland ch1 - answer in 1901
Signal ch1 - answer we mean electromagnetic waves to transmit
information
Analog signal ch1 - answer signal intensity varies in a smooth fashion
over time(No breaks or discontinuities in the signal)
Digital signal ch1 - answer signal intensity maintains a constant level for
some period of time and then changes to another constant level
Periodic signal ch1 - answer analog or digital signal pattern that repeats
over time
, Digital data, digital signal ch1 - answer Equipment for encoding is less
expensive than digital-
to-analog equipment
Analog data, digital signal ch1 - answer Conversion permits use of
modern digital transmission and switching equipment
Digital data, analog signal ch1 - answer Some transmission media will
only propagate analog
signals
Analog data, analog signal ch1 - answer Analog data easily converted to
analog signal
Transmission Medium ch1 - answer Physical path between transmitter
and receiver
Guided Media ch1 - answer Waves are guided along a solid medium
Unguided Media ch1 - answer means of transmission but does not
guide
electromagnetic signals
