6. The signals in Fig. Q3 (a)-(c) are modulated signals with carrier \( \cos 10 \mathrm{t} \). Find the Fourier transforms of these signals using appropriate properties of the Fourier transform and the FT table.

(a) the signal is, -pi+pi01 here the signal g(t) in this case is a triangle pulse ?(t2?)multiplied by cos10t g(t)=?(t2?)cos?10t also from table, ?(t2?
