I moved this to the homework forums. Angel23, as you know, you need to show some of your own work to get help from the PF community. What are the definitions of DSP with and without memory?

 

[angel23]

ok a memoryless system is the system in which the value of output at t1 depends only on the value of the input at t1.

now i want to apply this on the given system how can i do?

Let t1= (n+1)*T and see if your definition applies.

Yes, since Y[t1] depends on T[t1-T].
