这里讨论了一种晶体管延迟线路。线路的工作原理是用一单稳多谐振荡器的时基电容通过一恒流器件放电。这个恒流器件是一个工作在共基型的晶体管。线路产生一矩形脉冲,它的宽度在很大范围内正比于一直流控制电压。它还产生具有良好线性度的线性扫描电压。可得到的脉冲宽度范围很大。线性扫描的速度在一定范围内连续可变。 Here’s a transistor delay line. The working principle of the circuit is to discharge with a constant current device with the time-base capacitance of a monostable multivibrator. The constant current device is a transistor operating in a common base type. The line produces a rectangular pulse whose width is proportional to a DC control voltage over a wide range. It also produces a linear sweep voltage with good linearity. The range of pulse widths available is large. The speed of linear scanning is continuously variable over a range.
