I need to model the coupling coefficient of two inductors as a function of time. I tried using combination of .func and .param statements to pass a time varying variable to the spice K component

I think a distinction needs to be made between attacking the issue and attacking the user.. Cheers AG

Indeed, we should attack users, who attack users - it seems that this is the only language, those pseudo-masters will understand. Johannes Herrmann / Yahoo Micbuilders Group P.S. In our group, such an

The "Pick New Transistor" function is wonderful, allowing me to sort by key features for an easy selection of the available library of parts. Is there any way to access a selector menu like this for

Hello analogspiceman and all others, We shouldn't attack users when we don't know about their knowledge and capabilities. Please keep that in mind. Best regards, Helmut Moderator PS: Especially using

Tony You should have taken the hint by now that my query on modelling frequency dependence was done in total oblivion of Shivesh's original thread over which for some reason you keen wanting to remind

I mean the "View>Marching Waves" menu.

<snip> </snip> Hello Alan, Part of your problem can be sorted by disabling marching waves, either from the Simulation menu, or by adding: .option nomarch in the schematic. This speeds up long .tran

Hi there, as already posted by Helmut a while ago, Mike Engelhardt will come over to Germany to enlighten us on his LTSpice IV world tour. Although Stuttgart and Hannover are fully booked there are a

<snip> </snip> George, It's no more trivial than referring to the help file to find the correct syntax for using Laplace in dependent sources, which was the subject of your original question in this

That is true, and I have defined the space-bar to reload the settings, so it behaves similar to in the schematic editor. I have set the scales to make it easy to compare the voltages/currents in my

Guys all this is first year circuit theory. We all know and come across series to paarllel convertions of reactive networks that introduce FDR effects where the real part of the immitance function

FDR happen in all manner of nonlinear devices from ferrite cores to dielectrics where losses are a function of frequency. Try to model a ferrite core losses ( both series and ||Rs) with typical data
