Double Side Band with Suppressed Carrier (DSBSC) signal under Digital Sound Processing:
Amplitude modulation (AM) technology is used where the modulating signal is given as ?(?)=1+5.5cos(9600??) while the carrier is given as ?(?)=2cos(96000??)+4cos (144000??).
How do you obtain the receiver carrier and the bandwidth of the recovering filter so as to recover the modulating signal?

Problem No. 1: Let us consider that a baseband message signal m(t)=4cos(2000xt) has to be transmitted from a location 'A' to its destination 'B' using a carrier signal given by c(t)=2cos(10000#t). The signal s() m(t)c(i) is the modulated signal which will be transmitted. Consider that the signal is transmitted through a noiseless channel and received at the receiver at location 'B' as the signal s(t). Based on this information, perform the following tasks. 1. Find, sketch and label the spectrum...
