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

Re: How do I import the LMH6629 spice file into LTSpice IV?
Hello Jesper, My examples are for a universal symbol and a specific symbol. Please open the symbol files(.asy) with the symbol editor of LTspice and view the obvious differences in the attributes of

Re: How do I import the LMH6629 spice file into LTSpice IV?
Hi again Helmut, & thanks for uploading the new files :-) Incidentally, you've actually helped me with a challenge I've had on how to make a tiny circuitry to measure HF noise in DAC/ADC supply rails:

LTSpice & Eagle
Some background, not intended to be criticism, then the question. Cadsoftusa's Eagle 6.4 introduced an interface to link schematics with LTSpice IV for simulation. Unfortunately, the link does not
