FM | AM |
---|---|
Amp of FM is constant, it is independent of modulation index | Amp of AM wave will change with modulating vtg. |
Transmitted power remain constant, It is independent of Mf. | Transmitted power is dependent on modulation index |
All transmitted power is useful | Carrier power and one sideband power are useless |
B.W = 2[S + fm]. It depends on modulation index | B.W = 2fm does not depend on modulation index |
Complex equipment required. | Equipment required are less complex |
