Hi guys,

I am new to matlab and am having problem plotting a carrier

signal,multiplting my message signal and carrier signal and plotting

the resulting doublesideband suppress carrier.

Am having problem choosing the right sample frequency.either I have too

much waveform in the figure or i dont have enough.

my carrier signal is c*cos(2*pi*fc*t).amp(Ac)=1.8V, freq(fc)0khz.

my message signal is m=Am*cos(2*pi*fm*t).Am=1.8V,fm=1khz

I need to plot these two signals and multiply them to give a dsbsc and

plot it. Can you please help me with the right commands I should use.

Regards

Azeez
