Tutorial 7 Exercise 1) Let consider a discrete Linear Time Invariant system (LTI) describe by the following difference equation: y (n )+2y (n-1)=x (n)+2x (n-1) 1. Represent the structure of the system 2- Determine the transfer function of the system. 3. Determine the type of this filter (IIR, RIF), justify. 4- Study the stability of the filter 2)Given the following FIR filter represented by the difference equation. x(n) + x(n-1) 2 1- Represent the structure of the system 2- Determine the transfer function of the system. 4- Study the stability of the filter 5- Determine and draw the impulse response of the filter
