摘要：
A ground continuity circuit is described. In one embodiment, a first voltage of a signal associated with an electrical line input to a circuit is measured with respect to a first resistance value of the circuit. A ground continuity test signal is asserted into the circuit that causes the resistance value of the circuit to change to a second resistance value. A second voltage of the signal is measured with respect to the second resistance value. A ground impedance value of the circuit is determined as a function of the first and second measured voltages and the first and second resistance values.
