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.
