Abstract
PURPOSE: To enable to correctly grasp the signal having rapid change in the peak value, by displaying the maximum peak value up to the immediately before the signal as well as the peak value of the input signal.
CONSTITUTION: The peak value of audio signal amplifier 1 is detected 2 and it is tentatively ketp at the recovery circuit 3. On the other hand the maximum peak value of signal in the circuit 3 is stored in the circuit 4. Further, if the peak value of input signal is greater than the signal value stored in the memory circuit 2, the output of the reset timing detection circuit 6 operates the reset circuit 5 to keep the memory state of the circuit 4. If the input signal is smaller, the input signal is fed to the display 13 via the switch 8 and the signal in the circuit 4 is via the switch 9. In this case, the amount of passage of the switches 8 and 9 is controlled to display brightly for the input signal and darkly for the maximum peak valve. Thus, the maximum peak value of the input signal can easily be known.
