Hello Gene, You have to click the "button" below the 31.98. It's enabled after 10 seconds. Best regards, Helmut

Re: My collection of models and examples for LTspice.
Hello, Neither this 31.98Meg nor the previous 98Meg files appear to have working links. I see a timer that counts down and only when it reaches 0 is there a box that may be a link, but the downloaded

Re: Monostable VCO Schmitt problem
How much fluff would be added with a line in the help like: SpiceLine: Vt=0.5 Vh=0.1m When someone does not use LTspice very often (in my case, intensively 2 or 3 times a year) I cannot even remember

Re: Monostable VCO Schmitt problem
Yes, Help, although fairly extensive, is not complete. The LTwiki documents many of the missing items. Since you seem willing and able, here is a big hint on how to use LTspice itself to answer

Re: Monostable VCO Schmitt problem
LTspice Help is written primarily as a terse reference guide (with a few examples thrown in). Usually all the information required to use a feature is included, albeit in a very condensed form. Mike

Re: Monostable VCO Schmitt problem
I have found the instance parameters and Spiceline and Spiceline2 to be totally incomprehensible. I think it assumes a familiarity with ancient_spice which Mike thoroughly refuses to detail in the

Re: Monostable VCO Schmitt problem
Actually, the Help file was the first place I went hunting and found this: At that point I searched for "instance parameters", and one of the several pages I investigated was titled "Adding

Re: Averaging a waveform
Mike Engelhardt has stated that he is philosophically opposed to such imprecise functions. What is average? Is it an analog low pass filter function or a numerical sliding average? What order is it

Re: Monostable VCO Schmitt problem
Try reading the Help file next time before spamming the group with your needlessly ignorant drivel. Quoting Help: ________________________________________________________ The gates default to 0V/1V

Re: Averaging a waveform
Hello Jim. Unfortunately it's not possible to directly define a formula with integration in the waveform viewer. One has to make a Bv-source in the schematic or netlist. .param d=100u .func avgx(x,d)

Monostable VCO Schmitt problem
Hi all. I've just uploaded a file "Monostable VCO Schmitt problem.asc". The simulation works when a INV is used, but has problems when a SCHMITT inverter is used instead. Both use default values, and

Re: Averaging a waveform
Jim, I'm surprised you haven't looked at the LTspice help file. This is in the help under Waveform Viewer>Waveform Arithmetic. Rick

Averaging a waveform
Is there any way, in a LTspice plot, to _display_ the average of a waveform over a specified interval? Something like the AVGX mechanism in PSpice's Probe? -Jim Thompson
