A wave shaping circuit is provided having an input node, an output node and a ground node. A first circuit is connected between the input and ground nodes, and a second circuit is connected between the output and ground nodes. The circuits operate so that in a first mode, such as at low RMS line voltage, a V1 signal passes through the wave shaping circuit without being modified as to shape. In a second mode, such as at high RMS line voltage, the line voltage signals are modified to provide flattening of the peak of a waveform provided at the output node. <IMAGE> |
