please answer both questions 4 and 5

Given the signal x(n) and h(n) presented in the figure below, analyse, compute and plot the convoluted signal y(n) using the table method. Remember: y(n)=+h(1)x(n+1)+h(0)x(n)+h(1)x(n1)+h(2)x(n2)+=k=h(k)x(nk) x(n)=[4,2,1,0.5,0.25]andh(n)=[0,1,1] A given periodic signal x(t) is sample at 1000 Hz in 5 data points define as presented in the table 1-Compute and plot the sampled signal x(t) in time domain [2] 2-Compute the Fourier Transform coefficient of X(n) [5] 3-Compute and plot the amplitude spectrum of X(n) [7] 4-Compute and plot the phase spectrum of X(n) [7] 5-Compute and plot the power spectrum of X(n) [7]
