2) You are asked to design a DSB-SC modulator to generate a modulated signal km(t) cos wet, where m(t) is a signal band-limited to B Hz. Figure below shows a DSB-SC modulator available in the stock room. The carrier generator available generates not cos w̟t, but cos³ w̟t. M(f) km(t)cos³ wet m(t) A Filter f -B B cos w̟t Sketch the signal spectra at points a and b. Is it possible to realize a DSB-SC modulator as in the figure above? (If yes) what kind of filter b) should be used? Comment on the bandwidth of the filter and the minimum and/or maximum frequencies that the filter should allow to pass. c) What is the minimum usable value of wc? a=1 , b=8, c=0, d=9,e=0_f=0 g=0 h=6 i=2|
