The frequency response Hf(w) of a discrete-time LTI system is as shown. Hf(w) is real-valued so the phase is 0. Find the output y(n) when the input x(n) is x(n) = 1+cos(0.3πn). Put y(n) in simplest real form (your answer should not contain j)
Consider a discrete-time system that is linear (but not necessarily time-invariant), and where: - if the input x[n] is even, then the output is y[n]= x[n-1] - if the input x[n] is odd, then the output y[n]= x [n=1] Find the ouput of this system if the inpus is (a) δ [n] (b) u[n]. (Do not use la place transform) Hint: if a signal is neither even nor odd, then you can write it as a sum of an even...
