Find the CTFS coefficients of x(t) (using direct calculations), and those of its integral (using CTFS properties). Use the found CTFS coefficients to generate and plot the integral signal of x(t).

Q4. Find and plot (as a function of F) the magnitude of the response, y[n], to the periodic excitation x[n] = cos(2πFn) for the system described by

y[n]= x[n] + 0.9 y[n-1].
