Consider an AM signal with additive white Gaussian noise having a power spectral density 0 =101W / Hz . The message signal is periodic signal shown in the flowing figure and is 2. limited by bandwidth of 4KHZ. m(t) 0.5 Ims 2ms 1-0.5 a. Using 100% modulation (no distortion), find the minimum carrier amplitude value A that will yield (SNR)..AM 2 60dB b. If carrier signal c(t)= 2 cos(27400001) and k, = 0.5, find (SNR) (SNR), and C,AM Figure of Merit.
