Strange response in a circuit - need verification

Strange resp.

why such strange result !!!!!!!!!!!

it should be only one tone ???

Hello ahmed osama,

Have you changed step size of your simulation?

I think that your result may be an artifact due to undersampling.

Hope this helps,

Kind regards.

Hello,
if your frequency source is f1, the time step of simulator must > 1/(2f1) (Nyquist theorem).
So f1=100MHz, like your circuits, the time step must be > 5nsec.
Kind regards.

Hello,
> 5nsec.
Kind regards.

< 5ns

Hi,
I got the response for the same circuit.

just listern and modify settings for proper response.

Bye.

Hai,

I explained with Vsource. If you are using Isource, then your response curve is correct.

response due to high frequency and reactive component. Also depends on connection RLC parallel circuit (RL ll C ll R).

Before doing simulation, you should sure about your requirements. otherwise the response seems to be strange eventhough its right.

Bye.

if you use a ideal vsource as supply, other component are useless

Hi,

If a small value of R connected series with source, then the effect is negligible with respect to L and R.

since compare with XL and R values.

XC value raise is not collaps the response.

Eventhough if you are expecting high accurate result the the source internal R should be there.

Bye.
