For an AM signal with multi-tone modulation, the modulating signal is given

For an AM signal with multi-tone modulation, the modulating signal is given by m(1) = !! 4 cos omt + 2 cos 20mt and the carrier is given by c(t) = 5 cos o,t, where m, > Om Does the AM signal satisfy the envelope-detection criterion? Find an expression for and sketch PAM (0), the spectrum of the modulated signal.
