Abstract
PURPOSE:To detect signal power for a consecutive modulation wave and a fault of a signal transmission system by outputting a digital value in response to an input signal level periodically even in the consecutive signal state or a non signal state. CONSTITUTION:A comparison means 11 compares an input signal voltage with a reference voltage and a delay means 13 generates a pulse in a delay timing of a prescribed time in response to the comparison output. An analog/digital conversion means 15 applies the analog/digital conversion of the input signal voltage in the input timing of the pulse. A count means 17 starts time counting in the conversion operation timing of the analog/digital conversion means 15 and sends a conversion control signal to the analog/digital conversion means 15 when the count reaches a prescribed count.
