This Is DSP Lab 3 How to Produce Beat Note in Matlab Learning Objectives: How to plot in matlab How to make multiplots in a single window How subplot works Multiplication of signals Beat note Code: t=0:0.0001:1; x1=cos(2*pi*90*t); x2=cos(2*pi*9*t); y=x1*x2; subplot(2,1,1) title('sinusoids of Different frequency'); plot(t,x1, 'linewidth', 2); hold on plot(t,x2,'r', 'linewidth', 2) subplot(2,1,2); title('Multiplied signals result'); plot(t,y,'r', 'linewidth', 2) hold on plot(t,x2, 'b','linewidth', 2); hold on x3=cos(2*pi*9*t-pi); plot(t,x3,'b', 'linewidth', 2) sound(y)
