I saw this filter shown in the screenshot in SIMULINK but i can't understand the meaning of this filter. The Ts is the sample time. What changes it will cause in signal I ?

Please try it for yourself in Simulink and if you have further questions please ask.

You have a discrete linear system. You could find the system transfer function by analysing the system. It turns out to be a first order IIR filter with one pole . With appropriate parameter Ts ( is a function of Ts), it can be a low pass IIR filter. This explain why your output is a smoothed out version of input.
