4. A spectrum of the low-pass message signal modulating the harmonic carrier with the frequency fe (fefmax) is given in the following picture. M(ƒ) 1 Imax -fmin fmin fmax f Draw the spectrum of the modulated signal for: a) amplitude modulation AM; b) double-sideband modulation DSB-SC; c) single-sideband modulation SSB-LSB (lower sideband).
