Claims (1)
続された表示回路と、該表示回路と並列に接続された電
源電圧減少状態検出回路とを備え、前記表示回路及び前
記電源電圧減少状態検出回路に印加される電源電圧が充
分高い場合には、前記電源電圧減少状態検出回路をオフ
すると共に前記２表示回路にて前記増幅器へ印加される
入力信号のレベルを表示するようにし、電源電圧が一定
値以下に減少した場合には、前記電源電圧減少状態検出
回路をオンし、その出力を前記増幅器の出力に重量して
前記表示回路に印加することにより前記表示回路を飽和
状態となし、以って前記表示回路にて電源電圧が減少し
たことを表示するようにした入力レベル兼電源電圧減少
状態表示回路。An amplifier to which an input signal is applied, a display circuit connected to an output end of the amplifier, and a power supply voltage reduction state detection circuit connected in parallel with the display circuit, the display circuit and the power supply voltage reduction state detection circuit being connected in parallel to the display circuit. When the power supply voltage applied to the detection circuit is sufficiently high, the power supply voltage decrease state detection circuit is turned off and the level of the input signal applied to the amplifier is displayed on the second display circuit, and the power supply voltage is decreases below a certain value, the power supply voltage decrease state detection circuit is turned on, and its output is added to the output of the amplifier and applied to the display circuit, thereby bringing the display circuit into a saturated state; Therefore, the input level and power supply voltage reduction state display circuit is configured to display that the power supply voltage has decreased in the display circuit.
