transfer function from circuit

[hoki222]

Hi,

is it possible to receive a transfer function from for example a simple lowpass RC-circuit or does it just work vice versa?

Hi Hoki,

you can't get the equation from a Transfer Function of your circuit. You can just use known TFs.

hoki22,

Standard R,L,C transfer functions are of the rational polynomial form F(s) =A * (1-s/Wz1)(1-s/Wz2).../(1-s/Wp1)(1-s/Wp2)...

where Wz1, Wz2.. are your zeros and Wp1,Wp2...are your poles.

If your Multisim tier allows it, you can run Pole-Zero analysis to determine these values and plug them into the equation (although you would still be required to determine the gain value A).

Hope that helps.

Hello,

I ask you how it's possible to create transfer functions of attached thermal model with labview, in order to simulate temperatures in T1 and T2.

P expressed in Watt

R expressed in Kelvin/Watt

C expressed in Joule/Kelvin
