Abstract

PURPOSE: To display the condition of silence with volume zero and the condition present in the volume with different colors each other on the color receiving tube.
CONSTITUTION: The circuit of the sound volume display 4 and silent bar display 5 is the AND circuit of negative logic with diodes and transistors, and the output of negative logic is fed to the base of the drive element via diodes. The signal of the volume sound display control circuit 1 and the level of the integration output 23 of the pulse pressence judging circuit 3 are detected, and the output pulse 11 of the pulse width modulation is silent with the silent tone switch operated and the integration output is zero volt. AND is taken when the signal from the circuit 1 is zero, the output 30 is increased by applying it to the element 35 and applied to the cathode of R-Y of the receiving tube 6, allowing to display red bar display which indicates no sound. On the other hand, in the sound bar display, the signal 28 inverting the signal 23 with the transistor 36 and the control signal from the circuit 1 when the pulse width modulation output pulse 11 is present are in agreement (AND) with the transistor 37 and the output 29 is applied to the cathode of G-Y after being increased and green sound volume is displayed for bar display.
