A signal s(t) has the spectrum shown below. S(J) 2jx Write the equation for s(t). Can you sketch this signal? 0.5 √ (Hz) You have been asked to assist the designer of a power transmission system. In a symmetric three-phase system, the sum of the instantaneous currents in the three phases is supposed to be zero. The instantaneous currents in each of the three phases are defined as: i(t) Acos(2 fot + 1) i2(t) = A cos(2π fot + 2) i3(t) = A cos(2 fot + 3) The system frequency fo is 60 Hz. The amplitude A varies between 10 and 1000. The designer has chosen 1 = 0. Your task is to determine values for 2 and 3 such that i₁(t) + 2(t) + i3(t) = 0) or to prove that no values of 2 and 3 will guarantee that the sum of the currents is zero. Choice of 2 and 3:
