Suppose a communications system that transmits a user's information, given by the following signal: x(t) = 3cos(2n · 200t) + 5cos(2n · 300t). The system uses a carrierless dual sideband modulation, multiplying the signal by a 200kHz frequency cosenoidal carrier. At the receiver, the signal is multiplied by a 5okHz carrier and then passed through a (ideal) pass filter, with a bandwidth equal to 2kHz and centered at a frequency of 250kHz. x(t) Band Pass 3 Cos(2* pi*2000000t) Cos(2*pi*50000t)
