In order to be transmitted over a communication system, a speech signal with frequencies in the range 0.2-5 kHz is amplitude modulated over a carrier wave of frequency 1000 kHz. What would be the maximum transmitted frequency?
A) 5 kHz
B) 1000 kHz
C) 1000.2 kHz
D) 1005 kHz
Correct Answer:
D
Solution :
Frequency of side band \[=(v+\Delta v)\] = 1000 + 5 = 1005
