WebThese frequencies are side bands.Lower side band frequency = Upper side band frequency = where, is the carrier wave frequency and is the modulating/audio signal frequency. … WebSide bands are produced during the process of modulation. During modulation, the audio frequency modulating signal wave is superimposed on a high frequency wave called carrier wave. Any form of modulation produces frequencies that are the sum and difference of …
WebRadio waves are produced by the rapid movement of charges. These waves have low power levels and low frequencies ranging from about 3 kHz to about 300 GHz. Radio waves have 9 bands depending on the frequencies. Radio waves are used in radio communications, radar, computer systems, broadcasts, multi-channel frames, and many … WebLook at width of side bands above. But, remember when the three are added together a constant frequency wave is produced. Extra: Any of the two can be used to to retrieve message by transmitting (a) both the side bands (b) only one side band Usually due to economic reasons only the upper or lower side bands of an AM is often transmitted.

WebSolution. Verified by Toppr. Correct option is B) Lower side frequency of Amplitude modulated (AM) wave is 2ω c−ω m. Upper side frequency of Amplitude modulated wave is 2ω c+ω m. ω c,ω m are carrier and modulated signal frequencies respectively. Signal frequency 2ω m is present in the side bands. Thus AM wave has bandwidth of 2ω c+ω ...
