Karl and Nick,
?
It was I who dropped the original post asking about alternatives to LT Spice. Because I don't like to clutter up the threads, if someone does not respond after a day or two, I drop the message.
?
In this case, Karl, I am most grateful you provided your response and underlying video. Please know that your video provided a great deal of answers. Actually, it almost directly addressed my grief with LT Spice. Turns out I was having fits with the plotting that LT did and the resulting scales. FOR THE LIFE OF ME, I could not get the starting point, ending point, and ticks of an LPF analysis to cover the full desired range. That said, it lies in the type of analyes done, and the octaves (harmonics) options.?
?
I've saved your video, Karl, and careful review should amp up my skill level with LT Spice greatly.
?
A side remark, at approximately 1:10 in the video, you remarked that LT Spice was designed by engineers explaining the raggedy interface as opposed to software designed by someone used to creating "normal human" interfaces.
?
I am a software developer of over 45 years and remember wondering why Fortran was so obtuse versus the COBOL or C/C++ or other code I wrote! So then there's that!
?
Thanks again for your wonderful video and your time and help! I might offer some meager payback:
?
?
..it is a filter design tool somewhat like but not as complete as ELSIE. However, it designs complex filters and also offers to two options/conveniences:
?
(1) Will allow one to choose "standard" versus "exact" component values
(2) And allow the designed filters to be exported as either "Spice" or "QUCS" models.
?
Vielen dank fur die hilfe! My gratitude for the Rosetta Stone. If OK, I'd like to bounce some questions off you as the mysteries clear.
?
