Mike, Thanks a lot, kindly share the uploaded link here.

Yes, I know. I have already uploaded such a schematic example </g/LTspice/files/z_groups.io/Examples/Apps/THD%20Notch%20Filter/THD_Notch_Test.zip> using one a few years go. It doesn't

To evaluate and quantize crossover distortion you can use a notch filter (RC bridge) to eliminate the fundamental frequency out of the output voltage. [email protected]> wrote:

The best way to handle different simulations, is to name the schematics differently.? Say, MySim_Tran.asc and MySim_AC.asc, which might be identical except for their simulation commands.? Then each

If your amp is in a high gain negative feedback loop, it can be harder to see the crossover distortion because the feedback look "eliminates" most of it.? Getting rid of that feedback would make it

Yes. To "see" it, as a distorted- looking sinewave, you need to make the distortion bad enough so that it stands out.? Visually looking at sinewaves, they generally need to be pretty bad for humans

You can also do this with a .DC analysis. With this it's also very easy to do a "wingspread" plot, which plots the incremental gain, which is very revealing. -- Regards, Tony

...and apply a very low input signal when running the transient test.

1.Use.TRAN analysis, not .AC, because that doesn't show non-linearity. 2. Check that the current through the output devices is very small with no input signal. -- This email has been checked for

If I build a Class B amplifier (all have cross over distortion) What do I have to do, to see cross over in a trace... All I get is a perfect looking sign wave... What would be the analysis and steps

Dave, I just uploaded the file "MF_VCpot.zip". I got tired of trying to allocate floating net names to different pots. I chose the pin name as "PC", because it is the Pot Control pin. Feel free to

Bumping this to the top I had uploaded a couple of circuits yesterday. Can an LTspice subcircuit guru help me with passing a parameter, as below? relay_driver: can use this subcircuit for each of the

@eT, I really appreciate your contribution here.I will use it in design.

That's usually the value that matters. At lower voltages, the (calculated) inductance is normally higher, because of the nonlinearity of the B-H curve. But the small-signal inductance (as measured by

That's because the circuit is in transient regime. You have to wait several minutes for the system to be in steady-state. Look how the voltages and currentsare asymmetrical vs. 0V/0A in the first

If you're talking about autotransformers with Si-iron laminate cores, then be careful with inductance measurements. John Woodgate kindly reminded me previously about relying on small-signa
