I am trying to undestand the following monostable oscilator.Is there any website where its explained how the circuit works,and what are the waveforms at the output and at the capacitor when we apply a positive pulse of short duration?

If i had a circuit of this type with C=100μF, Vγ=0.7V, VSat=10.5V,
R1=10kΩ, R2=10kΩ e R3=1kΩ, how could i determine the lenth output pulse(delta T) and how can i calculate the recovery time during which i should not apply another pulse in the input?

Thanks

 

Hello ac_dc_1

But. . . You say in your post: R1 = 10k, R2 = 10k and R3 = 1K ohm
What would R3??

In these cases it is faster to ask Google.com.

R3 is the resistor that connects point A to point B.
