You us Write code to compute the sum end plot (t y) plot reconstructed signals e) Fourier series of full-wave rectified sinusoid A full-wave rectified sinusoid is a sinusoidal signal where only the positive lobe is kept. It is often used in DC power supply design. Consider the following full-wave rectified sinusoid with a frequency of 50Hz: 240cos(2TUt 0.25 T), for 0 S t S 0.01 x(t) for 0.01 t 0.02 Write MATLAB code to plot x(t) for 0 S t S 0.5. write MATLAB code to compute and plot (2N+1) Fourier coefficients of x(t), a N, ao aN. Use N 40 Write MATLAB ode to plot the signal that is constructed from the above (2N+1) Fourier coefficients of x(t), [5 marks] END OF LAB 3

Explanation / Answer

t1 = 0:0.0001:0.01;

t2 = 0.01:0.0001:0.5;

x1 = 240*cos(2*3.14*t + 0.25*3.14);

x2 = 0*t2;

x = [x1,x2];

plot(x);

N = 40;

x_FFT = fft(x,N);

plot(x_FFT,2*N+1);

x_cap = ifft(x_FFT,N);

plot(x_cap);
