How to ensure a constant amplitude for a sin wave plot ?

I am doing my final year project with my simulink as shown above and the part that concerns me is this:

For example, I have set my amplitude and frequency as 0.1 and 10 respectively. Why is my graph not showing a constant amplitude of 0.1 sin wave graph ? Instead, it looked like this:

Any ideas?

I think if you increase the time resolution, that should solve your problem.

May I know how to this? Thanks in advance.

You can have a look at

It has a good discussion regarding what you should do.

Thanks a lot! It really helped! Now my amplitude is constant!
