The aforementioned five message signals are modulated by a carrier, c(t) = 2 cos(1000πt). Please plot five modulated signals, mk(t)c(t) s. t. k ∈ {1, 2, 3, 4, 5}, in the time domain. Further, please plot the corresponding five spectra in the frequency domain. Consider the both cases of amplitude modulation (AM) schemes.(a) Double-sideband suppressed carrier (DSB-SC) AM (b) Single-sideband (SSB)-SC AM, in particular, focusing on the upper-sideband (USB) AM (c) m4(t) = 11(40.5) (d) m5(t) = 4(4-05)
