Hi All,
I am very much new to modelling using active and passive components. I want to make a model in which input will be a pulse wave and the output will also be square wave of 500us width but only when the pulse goes from low to high. Please give some hint so that i can do it.

use 555 timer...i think.

I cant use it Olvine.... i need to develop using simple active and passive elemants....

 

you would need to make a flip flop of your own using transistor....
It would b very hectic..

 

Actually I need to model using basic components.......that's why i have posted this question....flip flops and programming will do the task in secs.........but I want using the basic ones.........

 

i am capable of delivering the required signal using a controlled voltage source, just by writing a condition in my Tool........ but that is not desirable..... i need using basics......

 

Your model could:
Apply the pulse through a resistor to a capacitor,
start the square-wave output,
sense when the capacitor has charged up to a threshold voltage,
stop the square-wave output.

Edit: Shouldn't this thread be in the 'Homework Help' forum?
