Realize signal processing systems described by the difference equation: y1(n)=1/2 [x(n)+x(n-1)] and y2(n)=1/2 [x(n)-x(n-1)] using Matlab. Assuming same input signal x(n)=sin(ωn) for various values of ω ={0,/6, ,3/2, 1.9/2} applied to both systems find the following: Obtain stem plots of y1(n) and y2(n) in each case. (15 Marks) Critically analyze y1(n) and y2(n) in terms of type of filter, maximum gain and cut off frequency. (Hint : The system can be tested by computing frequency response of the system).

Discrete Time Signal Processing Question 1. Consider an IIR filter A(1-2-1 cos ω0) 1-2cos ω02-1+2 I. Compute its impulse response using the difference equation with an impulse signal δ(n) as the input. Use trigonometric identities to simplify the result as much as you can 2. Draw the diagram showing the implementation of this filter in terms of adders, delays and multipliers Note: The IIR filter above generates a cosinusoidal signal when an impulse signal is applied at its input.] Question...
