Given the following message and carrier waves, determine the AM signal equation and (DSB-LC) bandwidth: m(t)=0.7cos(24.3kHz*t), c(t)=0.5cos(214E9Hz*t)
a. 0.5[1+0.5cos(210t)]cos(2110MHz*t), BW = 20kHz | ||
b. 0.5[1+1.4cos(24300t)]cos(214E9t), BW=8600Hz | ||
c. 0.7[1+0.5cos(25E3t)]cos(2110E3t), BW=10kHz | ||
d. 0.7[1+2cos(14GHz*t)]cos(24300Hz*t), BW=28kHz |
