Hello, I'm trying to build a circuit to offset and rectify a sine wave,

as seen in here: http://picpaste.com/Capture_elec-T46L4qLf.PNG

sine wave with Vp-p 12 v and 1 kh, offset dc volts are 2, 4,3,6 and graph the output.

how is the right way to build it in circuit-lab?

@dloksh,

Welcome to CL.

It will help to read the run the introductory video and read the Documentation.

:)

If you're too excited and wriggly to do that just now then follow these instructions:

Vac => use a Voltage Function Generator under Signal Sources. Set it to Sine. Set it to whatever amplitude your require. Note that in these signal sources, Amplitude = peak swing (not RMS and not peak to peak). Suggest setting frequency to 1kHz.

Vdc => use a Voltage source under Ideal Sources. Set it to whatever DC voltage you require.

Put down a resistor. Edit it's value to 4.7k.

Put down any normal diode (not zener, not LED, not photodiode).

Add a ground symbol.

Join them up. Make sure you join wires to the the ends of each component lead and get join dots where more than two wires join. Offset 4 way joins to clarify that they are joins and not crossings.

Save it.

Click on Simulate.

Click on Time Domain.

Set a Stop Time of 2ms.

Set a Time Step of 2us.

Leave Skip Initial = No

No tick in Sweep Parameter.

Click on whichever netname label you want to view.

Click on Run Time-Domain Simulation.

If It doesn't work click on Build and go back and check your circuit and wiring.

Common mistakes are incorrect wire joins, accidental copying and pasting of duplicate parts over themselves and accidental incorrect net name labelling such as giving two voltage sources the same net label which then shorts them together.

Try again.

Lastly, now you've got a bit of an idea how to drive CL, go and read the Documentation.

Have a play with some of the squillions circuits in CL.

Have fun.

Thank you very much for your help, i understood what i did wrong in my circuit.
