how to desing a frequency dependent voltage source in multisim?

Hi i am new to multisim and i need to simulate equivalent circuit of VLF frequency loop antenna using multisim. For that i need to design a AC voltage source whoes amplitude increases linearly with frequency.how can i create it?

Hi Farairo,

 

I'm not that great with circuitry myself but what I would do is search the internet for a schematic and then build it multisim.I found one example that might help http://www.geocities.com/b52__/vlf/vlf_circuit.htm

 

Hope this helps.

Hi there,

 

I looked around and it looks like someone has come up with an equivalent circuit for VLF loop antennaaes here:

http://sidstation.lionelloudet.homedns.org/antenna-theory-en.xhtml

I think that its possible to model this accurately in Multisim.

 

Otherwise, I'm sure that you can use a combination of passive RLCs to obtain the frequency response that you require.

 

Let us know if you come across any difficulties with Multisim.
