C1 6n8 T1, T2 KF507 Slide 6 Slide 7 Slide 8 The monostable
multivibrator has got one stable position. Switch over to unstable
position is able from this position. After a time it switch over
back by oneself to the stable position. The transistor T2 opened
after connection of supplying voltage. Current started passing
across his base. Voltage on collector of transistor T2 decrease on
a minimum value and transistor T1 became closed. To change of this
state, open transistor T1 by impulse, it leads to reduce of voltage
on T2 base and it closed him. After discharge of capacitor C1,
transistors back to the original position. We get an impulse on
outlet, which is given by time constant = R b. C This multivibrator
is used like a delaying element. Slide 9 Explain the function of
monostable multivibrator. What is the difference between unstable
and monostable multivibrator? Where in practice is used this flip-
flop circuit? Slide 10 Build up a monostable multivibrator on a
desk of printed wiring cuprextite. Measure a static voltage on all
electrodes of transistors T1, T2. Measure a course of voltage on
outlet by oscilloscope and plot this course to the graph. Slide 11
