  • LTspice: what they don't want you to know ...

    From Danny Beaudrie@21:1/5 to All on Sat Oct 10 20:47:14 2020
    Hello, I am trying to plot the time derivative of a signal in LTspice, but I have run into two issues.

    1st) I tried using the "ddt(x)" command as you suggested, but LTspice says it does not exist as a command.

    2nd) Using D(x) i get a derivative, but it is not a smooth graph. Rather it looks like a bunch of small steps even when the parent function is smooth.

    Can you help at all?

    Thanks!
