Extracted text: 2. A voice morphing system internally performs the filtering operation using the IR filter described by the difference equation y[n]+25/28 y[n-1]+13/ 56 y[n-2]+1/56 yln-3)= x[n]+2x[n-1]+3 x[n-2] find the following. i. Transfer function of the system. ii. Poles and zeros of the system. iii. Draw the z plane and check whether the system is stable or unstable iv. Draw the block diagram of Direct form-l and Direct-Il realization of the above transfer function.
