On radiating (sending out) and AM modulated signal, the total radiated power is due to energy carried by ωc, (ωc– ωm) and (ωc + ωm). Suggest ways to minimise cost of radiation without compromising on information.

This is a Short Answer Type Questions as classified in NCERT Exemplar
In amplitude modulated wave side frequency contain the information and from the question the power will be ωc, (ωc – ωm) and (ωc + ωm)
So to minimise cost of radiation we use both (ωc – ωm) and (ωc + ωm)
