Comment by periblepsis on What is the scope of this circuit?
I think you will need to write a lot more. I've no idea whatsoever about what you want to know, here. I'm completely clueless. Can you re-phase your question?
View ArticleComment by periblepsis on Can the SOP expression be the same as POS expression?
The only difference is that you write C+D (SOP) or (C+D) as (POS). Nothing wrong with that.

No, you cannot use encrypted models from other simulators (SIMPLIS) in LTspice. You may consider looking/asking in the LTspice group to see if anyone there can help you. There are some fantastic people...

I'd suspect this is a modified 8255 device. Pinout seem about right. Ceramic seems about right. Could be totally wrong. RFNA is always a good choice for dissolving crap like that. Nasty stuff, but it...

I don't think there's a bright-line answer -- or an objective reality -- that could tell you how to handle it. Either you are supposed to truncate, or round according to some rules. And if you round,...

@JuanDeCastro I added NOPs only because a larger context is needed to allow the pipeline stages to clear out. You could use other instructions if you want. But I think it would complicate things. The...

dee, I think you will need to narrow the question a bit. Just dumping out a photo'd sheet of pencil markings (erased, and re-drawn on, no less) and a homework page with a large set of solution values...

Market size, probably. Arduino appeals to a large audience of artists, makers, and so on. I don't know, but I would guess that is a much much larger market. Also, it's not simple to start an entire...

Acausal (something that isn't this) systems can't have a circuit. Not yet, anyway. Sine can be shifted both horizontal and vertically, though. Within limits. And if you count computers as circuits (I...

@Roh Seriously, with only 3.3 V available, unbridged, and the usual overhead voltage expectations, you'd be lucky to get 1 V peak (2 V pp) into the speaker. Maybe 60 mW total into 8 Ohms? Nowhere near...

ISAR has been around a long time (at least back to the 1980's.) Phased arrays can and do use software to pulse targets of interest rather than sweep. So there will be ongoing sweeps but also, as...

It's the diode capacitance. If you look at the model for the MUR460, you will see it given as CJO=126.4p. The time constant, taken together with your last resistor value, is about 125 ms.

A simple voltage divider using two resistors could just use the following formula for the midpoint voltage:$$V_{_\text{TH}}=\frac{V_2\cdot R_1+V_1\cdot R_2}{R_1+R_2}$$That's where \$V_2\$ is the...
