This is from my phone, so it may be abreviated and spelled poorly. Perhaps the problem is that the analog nature of the delay lines allows small errors to grow due to the very high gain. Maybe

That was easy thanks. Chris

Hello Chris, Place a "njf" on the schematic. Right-mouse click on it and take a model from the list. Best regards, Helmut

I am interested in building a pierce oscillator with a JFET to simulate the way a vacuum tube would behave in a pierce oscillator, but I don't see any JFET devices in the components section. Any

Hello, Vlad - I have always found it challenging to translate discrete digital filters back into the analog for simulation. It is very easy to make errors that are not obvious but which completely

Thank you for the directions, but I wouldn't have started something if I didn't have at least one clue about it :-) It's true that I can't say I'm an "expert", but I'll manage, somehow. The problem,

If you say so. Being no expert either (by far), here's what I know, in short: they're a cheaper approach to interpolators/decimators because they're multiplier-free (not that it would matter in

Use UF4007(SF4007), they are 1A, 1000V, 75nS Trr and cheap. 1n4148 have only 75volt reveres voltage. 10pcs. in series gives 10KV. I would use 11 to have som margen. The biggest problem with this kinds

Vlad asked: "At least does anyone know why the samples lose their constant-time values?" I think what you're asking is, why does the waveshape appear to lose its staircase appearance. Well it still is

Vlad, Still much confusion here ... I really don't know what a CIC filter is and how it is supposed to work. Do the eight lower stages act as integrators, similar to analog integrators? The delayed

Yes it is a FuG 200 Radar set. I like reverse engineering things to see how they work. I understand PPI its the other approaches that I find interesting. a stack of 1N4148's shudder a large stack

Hi Suusi

I need a simple 1 transistor circuit example with the transistor using a subckt and the attached file and location of file called out. I want to standardize my oth files to it. Please give example.
