In amplitude modulation, sinusoidal carrier frequency used is denoted by ωc and the signal frequency is denoted by ωm . The bandwidth (Δωm) of the signal is such that Δωm << ωmc . Which of the following frequencies is not contained in the modulated wave?
  • a)
    ωm + ωc
  • b)
    ωc + ωm
  • c)
    ωm
  • d)
    ωc
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
In amplitude modulation, sinusoidal carrier frequency used is denoted ...
Modulated wave has frequency range.
ω± ωm
∴ Since ωc >> ωm
∴ ωm is excluded.
