Abstract
PURPOSE: To make it possible to supervise sound-field characteristics, etc., with simple circuit constitution by displaying the actual time, maximum value and hold value of an input signal on a display board, by controlling a signal input and rectifying circuit simultaneously with one display-mode switch.
CONSTITUTION: An input analog signal is supplied via switch 2 to filter circuit 3 that has (n) frequency bands and n-divided signals are rectified by (n) rectifying- smooth devices in rectifying-smoothing circuit 4 and formed by multiplexer 5 with a signal from decoder 10 into (n) series signals, which are supplied to level-axis driving circuit 7 by way of buffer 6. The output signal of decoder 10 is supplied to frequency-axis driving circuit 9 and fixed display is made on display board 8. In this case, circuits 2 and 4 are controlled in accordance with the operation of display- mode switch SW to display the actual time, maximum value and hold value of the spectrum of the input signal.
