在广播、电视控制设备中,为了监视节目峰值音量动态,中国唱片厂试制了数字式峰值音量表。由于采用了开关电路及数字管显示,克服了动圈式转动系统因惯量大造成上升时间长,表面指示宽度有限,影响指示范围的扩展等缺
In the radio and television control equipment, in order to monitor the program peak volume dynamics, the Chinese record studio trial digital peak volume meter. Due to the adoption of the switch circuit and digital tube display, the invention overcomes the problem that the moving coil type rotating system has long rise time due to large inertia, limited surface indication width, lack of expansion of indicating range
