CHARGING PULSE GENERATING SYSTEM

摘要

PURPOSE:To minimize the overlap between the charging pulses by giving the phase difference between the charging pulses every time the charging information varies, and thus to minimize the capacity of the power source which is used for metering of the call meter. CONSTITUTION:The n-pieces of the output lead are set, and the charging pulse generated at each output lead plus charging information A and B to decide each period of P1 - PN are applied from outside. And the phase difference and the period are decided by memory 1, 2 and 3 for charging pulses P1 - PN. Then the phase difference is given between the charging pulses every time the charging information varies to minimize the overlap of the charging pulses. As a result, the capacity of the power source used for metering of the call meter can be minimized.
