Proteus simulation problem in simple pulse circuit.

[Svasaya]

Hi All
I am simulating a simple circuit in Proteus, you can see in the attachment.
Why is it the Output ofAVS1 not properly full wave rectified at the zerocrossings
other wise ideally should be, as a result the pulses at the output of Op amp are not
steady.
Is there any mistake in the circuit?
Can any one suggest.

Samir.

Samir,

I don't think there is any technical fault in your simulation.

Try the following :

 System --> Set Animation options and change the "Timestep per frame" and "Single step time" to a low value like 5m

This should improve the result.

Hope this helps.

Your sugesstion worked.
I changed the timestep to 10m.
