BC:3.4 Consider the LTI (linear time invariant) dis- crete time systems with the following impulse re- sponses, h[n]. For each system, determine whether or not the system is causal or noncausal and whether or not the system is FIR (finite impulse response) or IIR (infinite impulse response). Give a brief justifi- cation. a.) b.) h[n] = (100)¹-n sin (0.17n)u[n - 3] h[n] = (100)¹-n sin (0.17n)u[n +3] c.) h[n] = (100)¹-n sin (0.1πn) (u[n +3] - u[n - 3]) d.) h[n] = (121e-j0.15″)3-nu[n-3]-(121e-j0.15″)3—nu[n-17] e.) h[n] = (121e j0.15)3—nu[n-3]-(121e-j0.15″)17-nu[n-17]
