    • A tint control for a color television receiver comprising means for shifting the phase of the 3.58 MHz. subcarrier reference signal before applying it to a demodulator stage. The resistive element of a potentiometer is connected across a capacitor, one end of the capacitor being connected to ground. An inductor is connected between the end of the potentiometer remote from ground and the slicer thereof, the slider being coupled to the plate of a subcarrier amplifying tube by means of a second, seriesconnected capacitor. Proper selection of values for the inductor and capacitors allows the use of an inexpensive linear Potentiometer, while providing the desired ''''flat'''' response in the midrange of potentiometer adjustment.
    • 一种用于彩色电视接收机的色调控制器,包括用于使3.58MHz的相位移位的装置。 子载波参考信号,然后将其应用于解调器级。 电位器的电阻元件连接在电容器上,电容器的一端连接到地。 电感器连接在远离地面的电位器的端部和其切片器之间,滑块通过第二串联连接的电容器耦合到子载波放大管的板。 正确选择电感和电容器的值可以使用廉价的线性电位器,同时在电位器调节范围内提供所需的“平坦”响应。
