I'm looking to find the inductance values for the coils in a multisim
transformer.
Alright, I'm trying to simulate a simple diode modulator for a school
experiment and am stumped at simulating the IF can.
I understand how to make an IF can with two capacitors set in
resonance with the inductors in the transformer, only I'm stumped at
determining/setting the inductance values.
I've been trying to decipher multisims settings to find values for the
inductance formula:
L = N^2*(u*A)/length
Any help would be greatly appreciated. The experiment I'm looking to
simulate requires trials through stages for way more components than I
have.
Thanks again,
Alex

This is not a multisim specific problem. Its a generic spice transformer
".subckt" one. You need to set the values of a typical transformer
model, e.g.
.SUBCKT Transformer 1 2 3 4
L1 1 2 100.00u
L2 3 4 100.00u
c1 1 2 100p
c2 3 4 100p
K1 L1 L2 0.99
.ends
K is a mutal coupling facter.
