When frequency division multiplexing (FDM) is used to aggregate several modulated channels together, no separation between channels (i.e., use of guard channels) is required. True False Regarding amplitude modulation (AM), if the AM index, µ, is greater than 1, then the modulated passband signal will begin to show signs of signal distortion. True False Given the following AM modulated signal, determine the occupied frequency bandwidth (note: assume double-sideband large carrier (DSB-LC): s(t) = 4[1+0.95 cos(2π3000t)] cos(2π100E9t) a. Frequency bandwidth =...
