You are asked to design a DSB-SC modulator to generate a modulated signal km(t) cos w1, where m(t) is a signal band limited to B Hz. The figure shows an available DSB-SC modulator. The carrier generator available generates not cos w,t but cos' o,t. Explain whether you would be able to generate the desired signal using only this equipment. You may use any kind of filter you like. c) What is the minimum usable value of w. |M(o) m(1) km(t) cos wt Filter cos o -27B 2B (a) (b) You are asked to design a DSB-SC modulator to generate a modulated signal km(t) cos w1, where m(t) is a signal band limited to B Hz.
