Abstract
PURPOSE: To display accurately a mean level and crest level by changing over indication response characteristics of a unit for the level indication of an acoustic equipment, etc.
CONSTITUTION: The absolute value of an input alternating-current signal is detected 1 and supplied to charge-discharge circuit 2 to obtain a mean value voltage. At this time, charge-discharge circuit 3 obtains and outputs a crest-value voltage before circuit 2 obtains the mean-value voltage. Circuits 2 and 3 are put into operation by turning switches S1 and S2 ON. With S3 ON, a voltage is supplied to meter driver circuit 5 being attenuated 4 by a difference in potential between circuits 2 and 3, and meter 6 indicates the level by its output. Therefore, S1WS3 are adequately turned ON to indicate the mean value or crest value with accuracy.
