Hi,

I found this Pulsed Oscillator circuit--Attached.

I have been trying to simulate this using LTSpice before i put it together but i cannot seem to make it work?

Does the circuit work & can someone give me some advice on some component values to use if it does work?

I want a circuit using LM339 in order to get Vout(t'e if vin=0-5V,Vref=3V,Vout should be+/-3V square wave)
+/-Vsat=vef.
