1 Angle Modulation Angle modulation is the process in which the instantaneous angle of the carrier signal is changed according to the instantaneous amplitude of modulating or message signal. Carrier Signal‚ The instantane ous frequency is f i ( t ) = lim f ∆ t ( t ) ∆t → 0 1 d θ i (t ) 2π dt For an unmodulate d carrier‚ θ i ( t ) is = θ i ( t ) = 2π f c t + φ c ‚ where φ c is constant There are two ways of varying the angle of the carrier: By varying the frequency‚ ωc – Frequency
