Z transform of a periodic function
Posted:

Can anybody help me about the following problem? I need to obtain the ztransform of a periodic function. Function f(t) is "t/a" for t values in (0,a], "1" in (a,3a], "4  t/a" in(3a,5a], "1" in(5a,7a], "t/a  8" in(7a,8a] where a=pi/4. Note that this is one period and the period is 2*pi. The function repeats itself until infinity. I need to find the z transform of this time function as a rational fraction format (i.e. A(z)/B(z)). Is there anyone can help me?
