3. A function generator produces the rectangular waveform $x(t)$ shown in Fig. P3(a), which is input to the circuit shown in Fig. P3(b). The diode is ideal, i.e., it only passes positive cycles of the input signal $x_1(t)$. Obtain both the Fourier series representation of $v(t)$ as well as its Fourier transform $V(\omega)$.

Step 1
To find the Fourier series representation of x(t), we need to determine the coefficients of the sinusoidal components in the waveform. The rectangular waveform x(t) can be represented as a sum of odd harmonics: x(t) = A/2 + (A/π) * (sin(ωt) + (1/3)sin(3ωt) + Show more…
