MATLAB: Plot a fourier series representation of function

fourier seriesMATLAB

Best Answer

Check this code

t = linspace( -pi , pi );
y1 = zeros(size(t));
for i = 1:2:5
    y1 = y1 + (4/pi)*(sin(i*t)/i);
end
y2 = zeros(size(t));
for j= 1:2:39
    y2 = y2 + (4/pi)*(sin(j*t)/j);
end
subplot(2,1,1)
plot(t, y1)
subplot(2,1,2)
plot(t, y2)

MATLAB: I want to create 2 sinusoid signals and adding it then create time domain of it first signal amplitude 110 50hz second signal amplitude 10 250hz

t = (0:0.001:1); 
y1 = 110*sin(2*pi*50*t);
y2 = 10*sin(2*pi*250*t);
plot(t,y1,t,y2)

MATLAB: How to plot signal for equation given below

Try this

t = linspace(0, 10, 100);
w = 1;
a = 1;
y1 = sin(w*t)./t;
y2 = sin(a*t).*sinh(a*t)./(2*a^2);
y3 = (exp(-t)+exp(-3*t)).*heaviside(t);
subplot(3,1,1)
plot(t, y1)
