14. SSB signal is generated using the modulator working according to the phase method. Assuming that the information signal is a harmonic wave having the frequency fm and amplitude Am find the amplitude ratio between the amplitude of undesired component and the amplitude of desired component if: a) the phase shifters are set not precisely: ³-α=π/2+8, where 870; b) the amplitudes of the signals at the outputs of phase shifters are different: m₂(t)= aАcos(2πft-α), m₂(t) = bAcos(2πft-ß), atb; c) the carrier signals are not precisely in quadrature: (t)=Ą. cos 2nft, c₂(t)= A sin(2nft-A), A#0; d) the amplitudes of the carrier signals are different: (t) = A cos 2πft, c₂(t)= Ą₂ sin 2nft, A₁ A₂.
