Q. An expression for a sawtooth wave over the internal 0 ≤ t ≤ T0 is given by f(t) = At/T0. The student is encouraged to check the Fourier coefficients to be a₀ = A/2, an = 0 for all n, and b_n =-A/(nπ) for all n. The Fourier series for the sawtooth wave is then given by

Using MATLAB, with A = 10 and T₀ = 2 ms, plot the truncated series representations of the wave form f (5,t),which is the sum of the dc component plus the first 5 harmonics, and f(10,t), which is the sum of the dc component plus the first 10 harmonics.
