Hii☺
Q.what are sidebands of AM wave ?Compare AM with FM wave?
anyone please answer my question correctly✌❣don't unnecessary answer okk

Answer:
In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, that are the result of the modulation process. The sidebands carry the information transmitted by the radio signal. ... In some forms of AM, the carrier may be reduced, to save power.
comparison between AM and FM wave.
• In amplitude modulation (AM) , the amplitude of the carrier is modulated as per the message signal. The other aspects of the carrier wave such as frequency phase etc. remain constant.
On the other hand, in frequency modulation (FM), only frequency of the carrier wave changes while amplitude, phase etc.
• The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
hope this will help you
