Hello,
im trying to create a signal that has a constant frequency but a changing amplitude.
Please help if you know.

Try these —
t = linspace(0, 10, 500);
s = sin(2*pi*t*10);
figure
subplot(3,1,1)
plot(t, s)
grid
ylim([-10 10])
title('Original Signal')
subplot(3,1,2)
plot(t, s .* t)
grid
ylim([-10 10])
title('Original Signal With Linearly-Increasing Amplitude')
subplot(3,1,3)
plot(t, s .* 5.*cos(2*pi*0.5*t))
grid
ylim([-10 10])
title('Original Signal With Periodically-Changing Amplitude')
.
