In an inductance-capacitance-resistance (LCR) series circuit, which is connected to an alternating current (a.c.) source of a frequency $\nu$, its signal voltage $v$ is equal to $v_x$ for an instantaneous time between 0 and half its time period $T$ and equal to zero during the next half period.
If $X_C = 2X_L = R$, calculate the total impedance of the circuit.
