Unformatted text preview: er to generate the SSB signals of the same relative magnitude ,it is convenient to multiply m(t) by 2cosw t. This is also avoids nuisance of the fractions ½ and yields the DSB-SC spectrum. Mw w Mw w We suppress the USB spectrum (above wc and below –wc) to obtain LSB spectrum. Similarly to obtain the USB, we suppress the LSB spectrum (between –wc and wc) from the DSB-SC spectrum. (a)From above figure, we can express ∅ cos 1100πt 2 cos 1300πt t 2 cos 700πt cos 900πt and ∅ t (b) From above figure, we can express...
