I'm not familiar with your schematic symbols. But I take it that \$U_q\$ is a voltage source with some polarity I cannot fathom. (No idea which end is positive.) Regardless, how could there be any...

@avian Thermal. Imagine a temperate increase for \$Q_1\$. Follow the implications through from there.

2 MeV beta sources are at the very high end of such emitters. I think 3 MeV is about as high as they go. The impacts are, by definition, random. What kind of answer are you hoping to see?? What exact...

There are many crystal based receivers, tube and semiconductor based, on the web. Have you looked, at all?

There are not separate state space variables when one of them is determined by the other one. So that's why you are having difficulties. They aren't free to vary independently since their sum must be...

@Larcron If you haven't already done so, you should include this 100 Ohm resistor for the LV25P output. It's effectively the source impedance as the LV25P should have an output impedance itself that is...

@kile There is no possible charge function possible that can be differentiated to generate the Meyer capacitance model. Can't be done. And Spice depends upon differentiation to get from A to B. So that...

@Larcron What kind of damping/Q and gain (if any) do you want in a 2nd order filter here? And by the way, what roll-off do you imagine getting with 100 Ohms and 1.9 uF? Looks like about 840 Hz to me....
View ArticleComment by periblepsis on Arduino can not drive a BJT connected to a relay
hrsk, Please provide a datasheet for the relay. Here's a table found in one such datasheet. Your relay may require more current. But this one doesn't seem like much current. So you don't need to drive...

Ann, two things are in my mind right now. The first is that I don't entirely trust how you are making measurements. Not that you are wrong. But the claim is sufficiently exceptional that I think a...

@Spencer What's the name of the textbook and its edition (and author(s))? Also, are you asking about the meaning of RMS? (It's all about power.) Finally, are you aware that you can analyze these kinds...

This is almost a good question. Not quite. Talk about the sample rate, please. Talk about the delay, too. And any allowable errors.
