Abstract
PURPOSE:To detect a signal power for consecutive modulated 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 state of a consecutive signal state or a no-signal state. CONSTITUTION:The leading of a burst wave or a consecutive modulated wave is detected and when an input signal voltage exceeds a reference voltage, analog /digital conversion is applied by a 1st control means 15 for a prescribed period to send a digital output. Moreover, when the input signal voltage reaches a reference voltage or below and the voltage keeps the reference voltage or below even after a prescribed time elapses, a 2nd control means 17 applies analog/ digital conversion to send a digital value. Moreover, the digital value subjected to analog/digital conversion is aborted at the leading of the input signal voltage or the trailing in the transient reply state by the processing of the digital value control means 19.
