摘要： An apparatus for measuring energy consumption includes an input circuit and a processing circuit. The input circuit is operable to generate a first digital signal representative of a line voltage waveform and a second digital signal representative of a line current waveform. The processing circuit is operable to generate energy consumption data based on the first digital signal and the second digital signal. The processing circuit is further operable to generate a first pulse waveform having a plurality of output pulses based on the energy consumption data, each output pulse corresponding to a quantity of energy consumed, the first pulse waveform having a select one of a plurality of modes. The processing circuit is further operable to provide the first pulse waveform to a meter output.
