Re: abcd for cable modeling
i'm working with power line communication systems. The articles explain the trasmission line theory for cable modelling, but then start to talk about abcd matrix and the advantage to describe the

Re: abcd for cable modeling
Instead of a matrix representation, you can use the normal transmission line that is built into LTspice. At those low frequencies, it should work well. So I'm wondering what sort of "cable" you need

Re: abcd for cable modeling
I need to simulate the cable behaviour between 90 kHz and 150 kHz. For these reason I think is always cited the abcd matrix and no others. How I have to go on if I choose to work with the a matrix? My

Re: Plot Settings
Hi Bob I always highlight the wave form pane and do a Ctrl S to save the settings. This will always display what ever was selected. But, the auto zooming is always there. Seems you cant turn that off

Plot Settings
When doing repeated simulations of a circuit with (for instance) different parameter steps, the plot settings revert to default settings each time, so I have to do: plot settings/reload plot settings.

abcd for cable modeling
Hello! I'm trying to model a cable in ltspice. I read some articles and everybody talk about the implementation of the ABCD matrix in spice. I will do the same but i don't understand how can i do...
