The signal y[n] = x1[n] + x2[n] + x3[n] is the sum of three periodic signals of %3D periods N1=2, N2=4, and N3=5, respectively. Then, the period of the signal y[n] is

! Required information x(t) A1 Az- The given figure is a graph of one fundamental period of a periodic function x(1). A CTFS harmonic function cxk] is found based on the representation time being the same as the fundamental period To, where A1 = 5, A2 = -3, and To = 5. If the representation period is changed to 3T0, determine the new numerical value of cx(0]. The new numerical value of c0] is 0.33 *

! Required information x(t) A - The given figure is a graph of one fundamental period of a periodic function x(f). A CTFS harmonic function cx[k] is found based on the representation time being the same as the fundamental period To, where A1 = 5, A2 = -3, and To = 5. Determine the numerical value of cx[0]. The numerical value of cx[O] is
