Question:
On radiating (sending out) an AM modulated signal, the total radiated power is due to energy carried by ωc, ωc – ωm & ωc + ωm. Suggest ways to minimise the cost of radiation without compromising on information
Solution:
Total radiated power due to energy carried by ωc, (ωc – ωm) and (ωc + ωm).
Sideband frequencies are generally close to the carrier frequency.
Only the sideband frequencies carry information in an amplitude modulated signal.
