Unformatted text preview: sin(3 t/ 7) + cos(2 t/ 5) + 2 sin(7 / 11 t ) . Is the total signal periodic? If so,Fnd the fundamental period of the total signal. What percentarge of the total power is contaned within each of the constituents? (b) Consider the signal x ( t ) = | t | for t ∈ [-π 2 , π 2 ] and x ( t ) = 0 for the rest of the period which is t ∈ [-π, π ]. Sketch the graph and Fnd the fourier coe±cients (2+1+2)+(3+5)=13...
