Question
The total harmonic distortion (THD) of a signal x(t) is defined as "the ratio of the total RMS-value of the
second and higher order harmonics to the RMS-value of the fundamental".
The THD of the voltage u:(t)= b-cosot + c-sin(5@t-n/3) [V] (b, c: Constants; b<1) is given as 20%. Hence:
a) Determine the relationship between a and b, if the form factor of the
voltage u(t)= 2+ a + u1(t) [V] (a>0, const.) is given as 1.2.
b) For a=1, calculate the active power drawn by the load in the figure.
