(a) (b) (c) (d) Sketch the spectra of m(t) = cos(2л50t) + 2 cos(27150t) and m(t) = sin (2n50t) sin (2n250t). Sketch and determine the spectrum of the DSB-SC signal of 2m(t) cos(2500t). From the spectrum found in Part (b), sketch the LSB and USB spectra. Find the time-domain expressions for QUSB (t) and PLSB (t).
