Physics Question on communication systems
For a single side band transmission a balanced modulator is used to
A
increase power of carrier wave
B
increase amplitude of carrier wave
C
suppress audio signal
D
suppress carrier component
Answer
suppress carrier component
Explanation
Solution
Since maximum part of the power of modulated wave is contained with the carrier wave which does not transmit any desired information, hence to avoid wastage of power to suppress carrier balanced modulator is used.
