Vpulse and Vsource

Hi Andrew,

 I was trying to simulate rectifier circuit for which I simulated the circuit to test with different inputs -Sine and Pulse.

Initially, I tried using Vpulse and I observed some result. Then, I replaced Vpulse with Vsine and observed some other result.

 Then I have replaced Vsine with Vsource so that I change the type of input by changing the properties.

I have used the same parameters in Vsource which I have used in Vpulse, but I observed those two results are varying in a huge manner.

Can you please let me know why the difference is happening so? 

In the attached zip file, you can see 5 images. First is the snapshot of the circuit, which I have used for simulation.

Second image is the plot which I have captured, when simulated the circuit using source voltage as Vpulse and third is the plot with Vsource.

Similarly, fourth and fifth plots are captured, when simulated the circuit using source voltage as Vpulse and Vsource respectively.

I have used the same simulation parameters but I do see a change in the plots.

Can you please let me know why it is happening so when I use Vpul and Vsource though I have used zero and one values same in both sources? I have used pulse width as 1.15ns.

Thanks,

Shahnaz.
