You are provided x[n] and h[n], which are defined as x[n] = δ[n − 1] + δ[n − 2] and h[n] = δ[n] − δ[n − 1] (a) Draw the input, impulse response and output of the system. (b) Calculate the frequency response of x[n], h[n], and y[n]. (c) Draw the magnitude of the frequency response of x[n], h[n], and y[n]. (d) Discuss their relationship between the time domain and frequency. (e) Discuss how the frequency response of the h[n] can infer how the filter is altering x[n].
