Question

Plot in Matlab the function below (add the functions) sin(x)+sin(3x)/3+sin(5x)/5+sin(7x)/7+... Amplitude is 4/1 here 1st harmonic 3rd harmonic 5th harmonic 7th harmonic 4 sin e sum 4 sin30 Зп amplitude 0 50 100 150 200 250 300 350 4 sin50 51 4 sin 70 71 -1.5 + 50 100 150 200 angle(degrees) 250 300 350 400

n=4;
x=linspace(0,360,200);
f=zeros(n,length(x));
for i=1:n
f(i,:)=sind((2*i-1)*x)/(2*i-1);
end
plot(x,sum(f))
grid on
xlabel('angle(degrees)')
