A=0.5;
f1=6;
f2=10;
fs=32*f1;
fs2=32*f2;
phase=16;
t1=0:1/fs:2-1/fs;
t2=1:2/fs2:3-1/fs2;
phi=phase*pi/180;
x1=A*cos(2*pi*f1*t1+phi);
subplot(2,1,1);
plot(t1,x1);
hold on;
stem(t1,x1);
xlabel('time s');
ylabel('Amplitude')
x2=A*cos(2*pi*f2*t2+phi);
subplot(2,1,2);
plot(t2,x2);
hold on;
stem(t2,x2);
xlabel('time s');
ylabel('Amplitude')
- sum of cosine wave with different frequenciesbuild the time domain
- build it with the magnitude spectrumso my code is correct or wrong?

OK What you looking for. As per your code, I have not seen any error. You have generated two cosine signal having frequencies in 6 & 10 with amplitude 0.5.
