There is a much simpler solution, you might prefer to perform Z transform of those. On the other hand, if that is not an option, you might try finding a common multiple between the signals periods.

You can read Schaum's Outlines for DSP, also I have some lecture talk about that but I don't Know the reference of them.

Sincerely,

• I think we can add zeros in any one signal and perform convolution,finally we can eliminate.

I got this proof fromSchaum's Book.Can't we apply this here?
