Idea of VSB Modulator • Pass-band (or High-pass) filter for USB-SSB modulation |H U (f)| f c f c • The filter below is much easier to design and implement 1 ✏ 1 1 ✏ f c f 1 f c f c + f 1
• Consider the two-tone message signal given as m(t) =A cos(2 f 1 t)+B cos(2 f 2 t) • Message signal multiplied by the carrier wave, that is, DSB signal e DSB (t) = (A cos(2 f 1 t)+B cos(2 f 2 t)) · cos(2 f c t) = 1 2 A cos(2 (f c + f 1 )t)+ 1 2 A cos(2 (f c f 1 )t) + 1 2 B sin(2 (f c + f 1 )t)+ 1 2 B sin(2 (f c f 1 )t)
