MAXIMUM AMPLITUDE LEVEL HOLDING APPARATUS, AND AUTOMATIC OUTPUT CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a maximum amplitude level holding apparatus which can hold accurately the maximum amplitude level by compensating voltage drop of a level detecting means for detecting peak.

SOLUTION: A delay part 5 delays an output signal from an operational amplifier 4 by a plurality of delayers connected in parallel to the operational amplifier. A level detection part 6 detects a peak level being a positive maximum amplitude level of each signal delayed by the delay part 5. A compensating part 7 compensates each voltage drop caused when the level detection part 6 detects the maximum amplitude level of each signal.
