43. Consider the following statements 1) The bandwidth of the A.M. wave depends on the bandwidth of the modulating signal. 2) The bandwidth of the A.M. wave depends on the modulation index. 3) The bandwidth of F.M. wave, for all practical purpose, depends on the modulation frequency. 4) The banwidth of FM wave, for all practical purpose, depends on the amplitude of the carrier. Of these statements, the correct statements are (A) (1) and (2) (B) (1) and (3) (C) (1) and (4) (D) (2) and (4)

  • Lekhika thankyou
    Bandwidth of A.M wave is, BW=2* fm= Twice of modulating frequency. and this band width does not depends on modulation index of AM. AND Bandwidth of F.M is , BW= 2*(∆f +fm) , i...
