Consider the following statement :

(i) The bandwidth of the A.M., wave depends on the band width of the modulating signal.

(ii) The bandwidth of the A.M., wave depends on the modulation index.

(iii) The bandwidth of the F.M, wave for all practical purpose depends on the amplitude of the carrier.

Of these statements the correct statements are

  1. (i, ii)
  2. (i, iii)
  3. (ii, iii)
  4. All of the above
