Question details

2. Determine whether the following difference equations represent FIR or IIR systems. For the FIR systems determine their impulse responses. (10 points) a. y[n]-0.3y[n-1]+0.09y[n-2] 2x[n]+x[n-2] b. yn] 0.25x[n-1]+0.5x[n-2]+ 0.25x[n-3] Let x[n]-3cos(0.5 n+60) + 2sin(0.3 n) be the input to the system in problem 2b. Find the output of the system (10 points)
