Question
Physics Question on communication systems
AM is used for broadcasting because
A
it requires less transmitting power compared with other systems
B
it is more noise immune than other modulation systems
C
its use avoids receiver complexity
D
no other modulation system can provide the necessary bandwidth faithful transmission
Answer
its use avoids receiver complexity
Explanation
Solution
AM is used for broadcasting because its use avoids receiver complexity. Only a diode and a capacitor are sufficient to separate the audio signal from the AM wave.
