I just started reading a Communications textbook [Principles of Electronic Communication Systems - Louis E. Frenzel-McGraw-Hill] , well in the first chapter[ch1:intro to electronic communication] the following questions (at the end of chapter) can not be solved, can you help ?
Why audio signals are not transmitted directly by electromagnetic waves ?
What is a generic synonym for radio ?
unrelated question:
I just want to learn the backgrounds to take "Electronic Communication intro" course and a "Microprocessors intro" course ?
What prerequisite courses (and textbooks~recommended) have the the above ?? tell me separatelly.
tell me eg. for first you need "general electronics - analog" & "general electronics - digital" bgd only.
